Abstract

Official abstract text for this publication.

The present invention provides an acid addition salt or a sodium salt of a compound represented by the formula (IA): or their hydrate or a stable crystalline solid thereof. The salt or the crystalline solid is extremely useful as an active ingredient for the production of a pharmaceutical product.

First claim

Opening claim text (preview).

The invention claimed is: 1. An acid addition salt or a sodium salt of a compound represented by formula (IA): or a hydrate of the acid addition salt or of the sodium salt, provided that the acid is 1) an acid having a substituted or unsubstituted benzenesulfonic acid group, which is at least one acid selected from the group consisting of p-toluenesulfonic acid, benzenesulfonic acid, trifluoromethyl benzenesulfonic acid, chlorobenzenesulfonic acid, and methoxybenzenesulfonic acid, or 2) a mixed acid comprising: the acid having a substituted or unsubstituted benzenesulfonic acid group; and at least one inorganic acid. 2. The acid addition salt or the hydrate thereof according to claim 1 . 3. The acid addition salt or the hydrate thereof according to claim 1 , wherein the acid addition salt is formed from acid selected from the group consisting of (i) p-toluenesulfonic acid, (ii) benzenesulfonic acid, and (iii) a combination of p-toluenesulfonic acid or benzenesulfonic acid, and an inorganic acid selected from the group consisting of sulfuric acid, hydrochloric acid, and hydrobromic acid. 4. The acid addition salt or the hydrate thereof according to claim 1 , wherein the salt is (i) p-toluenesulfonic acid salt, or (ii) a salt formed from a combination of p-toluenesulfonic acid and sulfuric acid. 5. The acid addition salt or the hydrate thereof according to claim 4 , comprising about 1.0 to 2.0 mole equivalents of p-toluenesulfonic acid relative to the compound of the formula (IA). 6. The acid addition salt or the hydrate thereof according to claim 4 , comprising: about 1.0 to 1.8 mole equivalents of p-toluenesulfonic acid; and about 0.1 to 0.5 mole equivalents of sulfuric acid, relative to the compound of the formula (IA). 7. The acid addition salt or the hydrate thereof according to claim 1 , which is a crystalline solid. 8. The acid addition salt or the hydrate thereof according to claim 4 , which is a crystalline solid. 9. The acid addition salt or the hydrate thereof according to claim 8 , which is a single phase crystal or a mixed crystal. 10. The hydrate according to claim 4 , wherein a content of water in the hydrate is in a range of about 12 to 17%. 11. The acid addition salt or the hydrate thereof according to claim 8 , wherein the crystalline solid is a mixed crystal comprising: a single phase crystal of 2 mole equivalents of p-toluenesulfonic acid salt or its hydrate, relative to the compound of the formula (IA); and a single phase crystal comprising: 1 mole equivalent of p-toluenesulfonic acid salt; and 0.5 mole equivalents of sulfuric acid salt or its hydrate, relative to the compound of the formula (IA). 12. The crystalline solid of the hydrate according to claim 7 , which is a mixed acid addition salt formed from 1.3 mole equivalents of p-toluenesulfonic acid and 0.35 mole equivalents of sulfuric acid, relative to the compound of the formula (IA). 13. The crystalline solid of the hydrate thereof according to claim 7 , comprising: about 20.2 to 23.2% of p-toluenesulfonic acid on an anhydrous basis; and about 3.5 to 5.0% sulfuric acid on an anhydrous basis. 14. The crystalline solid of the acid addition salt or the hydrate thereof according to claim 8 , wherein the crystalline solid has at least three peaks of diffraction angles (2θ) selected from the group consisting of 8.2°±0.2°, 10.1°±0.2°, 13.0°±0.2°, and 20.3°±0.2°, in an X-ray powder diffraction spectrum. 15. The crystalline solid according to claim 8 , wherein the crystalline solid has at least three peaks of diffraction angles (2θ) selected from the group consisting of 8.2°±0.2°, 8.9°±0.2°, 10.1°±0.2°, 11.4°±0.2°, 13.0°±0.2°, 19.9°±0.2°, 20.3°±0.2°, 21.5°±0.2°, and 26.2°±0.2°, in an X-ray powder diffraction spectrum. 16. The crystalline solid according to claim 8 , wherein the crystalline solid has at least three peaks of diffraction angles (2θ) selected from the group consisting of 8.2°±0.2°, 8.9°±0.2°, 10.1°±0.2°, 13.0°±0.2°, 16.5°±0.2°, 17.1°±0.2°, 17.9°±0.2°, 19.0°±0.2°, 20.3°±0.2°, and 26.2°±0.2°, in an X-ray powder diffraction spectrum. 17. A pharmaceutical composition comprising the acid addition salt or the hydrate thereof according to claim 1 , or a crystalline solid thereof. 18. A process for preparing the crystalline solid of the acid addition salt or the hydrate thereof according to claim 8 , comprising adding p-toluenesulfonic acid and sulfuric acid to a solution that comprises the compound of the formula (IA). 19. The process for preparing the crystalline solid according to claim 18 , wherein about 2.2 to 2.5 wt % of p-toluenesulfonic acid monohydrate and about 5 to 6 wt % of sulfuric acid are added to a column eluate that comprises the compound of the formula (IA). 20. The sodium salt or the hydrate thereof according to claim 1 . 21. The sodium salt or the hydrate thereof according to claim 20 , which is amorphous. 22. A pharmaceutical composition comprising the sodium salt or the hydrate thereof according to claim 20 . 23. The pharmaceutical composition according to claim 22 , which is a lyophilized formulation. 24. A method for preparing a lyophilized formulation comprising the sodium salt of the compound of the formula (IA) or the hydrate thereof, comprising: using a composition comprising the acid addition salt or the hydrate thereof according to claim 1 , or a crystalline solid thereof. 25.
