Abstract:
A polymorphic form of the compound 2-(R)-(1-(R)-(3,5-bis(trifluoromethyl)phenyl)ethoxy)-3-(S)-(4-fluoro)phenyl-4-(3-(5-oxo-1H,4H-1,2,4-triazolo)methylmorpholine characterized by an X-ray powder diffraction pattern with key reflections at approximately: 12.6, 16.7, 17.1, 17.2, 18.0, 20.1, 20.6, 21.1, 22.8, 23.9, and 24.8Â° (2 theta) which is substantially free of a polymorphic form of the compound 2-(R)-(1-(R)-(3,5-bis(trifluoromethyl)phenyl)ethoxy)-3-(S)-(4-fluoro)-phenyl-4-(3-(5-oxo-1H,4H-1,2,4-triazolo)methylmorpholine characterized by an X-ray powder diffraction pattern with key reflections at approximately: 12.0, 15.3, 16.6, 17.0, 17.6, 19.4, 20.0, 21.9, 23.6, 23.8, and 24.8Â°(2 theta).
