First claim

Opening claim text (preview).

What is claimed is: 1. A compound which is (4S)-3-{[2-(4-chloro-2-fluorophenoxy)pyrimidin-5-yl]methyl}-4-methyl-1,3-oxazolidine-2-one, or a salt thereof. 2. The compound according to claim 1 , which is crystalline (4S)-3-{[2-(4-chloro-2-fluorophenoxy)pyrimidin-5-yl]methyl}-4-methyl-1,3-oxazolidine-2-one characterized by a powder X-ray diffraction pattern comprising peaks at 5.4°±0.2°, 14.0°±0.2°, 16.3°±0.2°, 17.4°±0.2°, 18.6°±0.2°, 20.3°±0.2°, 21.0°±0.2°, 21.8°±0.2°, and 24.5°±0.2° degrees two theta. 3. The compound according to claim 1 , which is crystalline (4S)-3-{[2-(4-chloro-2-fluorophenoxy)pyrimidin-5-yl]methyl}-4-methyl-1,3-oxazolidine-2-one characterized by a powder X-ray diffraction pattern comprising at least three peaks at at least chosen from peaks at 5.4°±0.2°, 14.0°±0.2°, 16.3°±0.2°, 17.4°±0.2°, 18.6°±0.2°, 20.3°±0.2°, 21.0°±0.2°, 21.8°±0.2°, and 24.5°±0.2° degrees two theta. 4. The compound according to claim 1 , which is crystalline (4S)-3-{[2-(4-chloro-2-fluorophenoxy)pyrimidin-5-yl]methyl}-4-methyl-1,3-oxazolidine-2-one characterized by a powder X-ray diffraction pattern comprising at least four peaks chosen from peaks at 5.4°±0.2°, 14.0°±0.2°, 16.3°±0.2°, 17.4°±0.2°, 18.6°±0.2°, 20.3°±0.2°, 21.0°±0.2°, 21.8°±0.2°, and 24.5°±0.2° degrees two theta. 5. A pharmaceutical composition comprising (4S)-3-{[2-(4-chloro-2-fluorophenoxy)pyrimidin-5-yl]methyl}-4-methyl-1,3-oxazolidine-2-one or a salt thereof and a pharmaceutically acceptable carrier. 6.
