Procedure

Acetone (200 uL) was added to free-base version of 3-{8-(2,6-difluorophenyl)-2-[(1H-imidazol-2-ylmethyl)amino]-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-4-yl}-4-methyl-N-1,3-thiazol-2-ylbenzamide (25.1 mg), and the resulting mixture was heated to 50° C. Ethanesulfonic acid was added (1.0 equivalent; 1N in THF), and the mixture stirred for several days. The product was filtered, washed with acetone, and dried overnight in a vacuum oven at 50° C. with a slow nitrogen bleed. The yield was 70.6% (9.1 mg) of title compound with a melting onset at 296° C. (determined by DSC).
