Abstract:
The present invention relates to a process for the preparation of anhydrous crystalline 2-(R)-[(3-methyl-4-(2,2,2-trifluoroethoxy)-2-pyridinyl)methyl)sulfinyl]-1H-benzimidazole (dexlansoprazole).

Claim (Index 1):
A process for the preparation of crystalline anhydrous dexlansoprazole, characterized by an XRPD pattern having peaks at 7.5, 11.4, 13.1, 13.5, 15.1, 15.4, 17.3, 20.0, 21.7, 22.5, 24.0, 26.1, 27.3 and 28.6\u00b10.2\u00b0 in 2\u03b8, comprising:\n a) dispersing dexlansoprazole in one or more C 5 -C 9  alkanes or a mixture comprising one or more C 5 -C 9  alkanes and one or more C 1 -C 6  alcohols at a temperature of up to 50\u00b0 C. to produce a dispersion; \n b) cooling the dispersion to form a precipitate of crystalline anhydrous dexlansoprazole or \n azeotropically distilling the dispersion at a temperature of up to 50\u00b0 C. or \n azeotropically distilling the dispersion at a temperature of up to 50\u00b0 C. and cooling the dispersion to form a precipitate of crystalline anhydrous dexlansoprazole; and \n c) recovering the solid.
