Procedure

To a 1 L round-bottom flask equipped with a mechanical stirrer, a thermometer, and a condenser, 4 g of 4-methyl-N-[3-(4-methyl-imidazol-1-yl)-5-trifluoromethyl-phenyl]-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)-benzamide free base and 500 mL of ethyl acetate were charged. The slurry was stirred and heated to 76° C. (reflux) and held at that temperature for 40 minutes. To the resulting clear solution, 7.5 mL of 1 M benzene sulfonic acid solution (in ethyl acetate) was added. The mixture was stirred at 76° C. for 5 hours, cooled down to room temperature by natural cooling (cooling rate ˜0.5° C./min) and held at room temperature for ˜1 hour. The solid was collected by filtration and was dried at 50-55° C./10-20 torr for 8-16 hours to obtain 4-methyl-N-[3-(4-methyl-imidazol-1-yl)-5-trifluoromethyl-phenyl]-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)-benzamide mono benzyl sulfonate salt as a yellowish solid. Melting point=˜260° C.; x-ray diffraction pattern showing maxima at 2θ=6.5°, 7.8°, 9.4°, 10.4°, 13.7°, 17.0°, 17.5°, 17.9°, 18.8°, 21.2°.
