tert-Butyl 4-((2-cyanoethyl)(cyclopropyl)amino)-2-(4-(2-methyl-1H-imidazol-1-yl)phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (240 mg, 0.47 mmol) was dissolved in methanol (5 mL). Hydrochloric acid (0.014 mL, 0.47 mmol) was added and the reaction mixture was stirred at 80° C. for 1 h. The solvent was evaporated under reduced pressure and the crude 3-(cyclopropyl(2-(4-(2-methyl-1H-imidazol-1-yl)phenylamino)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4-yl)amino)propanenitrile (189 mg, 98%) was used as such in the subsequent step.
