tert-Butyl 2-methyl-2-(4-(2-(4-morpholinophenylamino)pyrimidin-4-yl)phenyl-carbamoyl)pyrrolidine-1-carboxylate (0.140 g, 0.250 mmoles), was dissolved in an ethyl acetate (5 ml) and methanol (1 ml) mixture. 4 M hydrogen chloride in 1,4-dioxane (0.625 ml, 2.5 mmoles, 10 equivalents, purchased from Sigma-Aldrich) was then added in a drop wise fashion over 5-10 minutes. Upon completion of addition, the reaction mixture was stirred at room temperature, and the progress of the reaction monitored by LC/MS. After 16 hours, additional 4M hydrogen chloride in 1,4-dioxane (0.312 ml, 1.25 mmoles, 5 equivalents) was added. After a total of 48 hours the reaction was complete and the resulting slurry was filtered off. The reaction flask was rinsed with ethyl acetate to ensure complete transfer of product. The resulting solid was washed with ethyl acetate (3×10 ml) and diethyl ether (2×25 ml) and dried under reduced pressure to give of 0.061 mg 2-methyl-N-(4-{2-[(4-morpholin-4-ylphenyl)amino]pyrimidin-4-yl}phenyl)prolinamide 367 as its hydrochloride salt (53% yield).
