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 methanol were charged. The slurry was stirred and heated to 64° C. and held at that temperature for ˜30 minutes. To the resulting clear solution, 7.5 mL of 1 M phosphorous acid solution (in methanol) was added. The mixture was stirred at 64° C. for one hour, cooled down to room temperature by natural cooling (cooling rate ˜0.5° C./min) and held at room temperature for 3-4 hours. The solid was collected by filtration and was dried at 50-55° C./10-20 ton 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 monophosphate salt (3.25 g) as a white solid. Melting point=˜208° C. (dec.); x-ray diffraction pattern showing maxima at 2θ=6.1°, 7.5°, 9.1°, 15.8°, 17.5°, 18.3°, 21.8°, 23.1°, 24.9°, 26.6°.
