Abstract

Official abstract text for this publication.

The present invention relates to novel mesylate salt of N-(5-(4-(4-((dimethylamino)methyl)-3-phenyl-1H-pyrazol-1-yl)pyrimidine-2-ylamino)-4-methoxy-2-morpholinophenyl)acrylamide, a novel crystalline form thereof, and a process for preparing the same. More specifically, the present invention relates to mesylate salt of N-(5-(4-(4-((dimethylamino)methyl)-3-phenyl-1H-pyrazol-1-yl)pyrimidine-2-ylamino)-4-methoxy-2-morpholinophenyl)acrylamide, which is excellent in stability, solubility, and bioavailability when it is administered not only alone but also in combination with other drugs and which has a high purity, a crystalline form thereof, and a process for preparing the same.

First claim

Opening claim text (preview).

What is claimed: 1. A process for preparing a mesylate salt of Formula 1 which comprises: (1) mixing the compound represented by the following Formula 2 and a single organic solvent or a mixed solvent, followed by adding methanesulfonic acid thereto, to prepare a mixture of the mesylate salt represented by the Formula 1; and (2) adding an organic solvent to the mixture to crystallize the mesylate salt according to Formula 1. 2. The process of claim 1 , wherein the single organic solvent used in the step (1) is one selected from the group consisting of acetone, methyl ethyl ketone, and ethyl acetate. 3. The process of claim 1 , wherein the mixed solvent used in the step (1) is a mixed solvent of water and at least one organic solvent selected from acetone and methyl ethyl ketone. 4. The process of claim 3 , wherein the mixed ratio of water and the organic solvent is 1:1 to 1:10 by volume. 5. The process of claim 1 , wherein the step (1) is carried out at a temperature of 20 to 70° C. 6. The process of claim 1 , wherein the step (1) is carried out at a temperature of 45 to 60° C. 7. The process of claim 1 , wherein the organic solvent used in the step (2) is at least one selected from the group consisting of acetone, methyl ethyl ketone, and ethyl acetate. 8. The process of claim 1 , wherein in the step (2), the organic solvent is added in a volume ranging from 3 mL to 20 mL based on 1 g of the compound represented by the Formula 2.
