tert-Butyl 2-(4-(2-methyl-1H-imidazol-1-yl)phenylamino)-4-(1-phenylethyl)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (612 mg, 1.20 mmol) was dissolved in methanol (10 mL). Hydrochloric acid (0.098 mL, 1.20 mmol) was added and the reaction mixture was stirred at 75° C. for 1 h. The solvent was evaporated under reduced pressure and the crude N-(4-(2-methyl-1H-imidazol-1-yl)phenyl)-4-(1-phenylethyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-2-amine (490 mg, 100%) was used as such in the subsequent step.
