Procedure

Added 320 uL of CH3CN to N-(3-{8-(2,6-difluorophenyl)-7-oxo-2-[(2,2,6,6-tetramethyl-4-piperidinyl)amino]-7,8-dihydropyrido[2,3-d]pyrimidin-4-yl}-4-methylphenyl)-3-thiophenecarboxamide (16.0 mg) and heated to about 60° C. Added methanesulfonic acid (1.1 eq; 1M in IPA), and solution clarified except for tiny amount stuck to bottom. After a few minutes at about 60° C., cooled to rt. Got lots of white precipitate. Stirred overnight at rt. Next day, filtered and dried to provide the title compound (3.5 mg). Melting point (tested with DSC) is 331° C.
