Procedure

The seventh embodiment of the present invention is directed to the benzene sulfonate salt of 4-methyl-N-[3-(4-methyl-imidazol-1-yl)-5-trifluoromethyl-phenyl]-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)-benzamide. This salt is reproducibly produced from ethyl acetate when one equivalent benzene sulfonic acid is used. The weight loss (room temperature to 250° C.) is about 0.63%, and the sample melts with decomposition at about 260° C. Its crystal structure ranges from poor to good. The XRPD pattern for the benzene sulfonate salt of 4-methyl-N-[3-(4-methyl-imidazol-1-yl)-5-trifluoromethyl-phenyl]-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)-benzamide is shown in FIG. 7.
