Procedure

Added 400 uL of acetone 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 (9.8 mg), mostly dissolved. Added hydrobromic acid (1.1 eq; 1M in water). After about 2.5 weeks, small amounts of crystals were seen. The cap was loosened and let to evaporate overnight. This resulted in more crystals the next day. To this was added back 50 uL of acetone, filtered and dried to provide the title compound.
