tert-Butyl 4-(ethyl((tetrahydrofuran-2-yl)methyl)amino)-2-(4-(2-methyl-1H-imidazol-1-yl)phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (253 mg, 0.47 mmol) was dissolved in methanol (3 mL). Hydrochloric acid (0.017 mL, 0.47 mmol) was added and the reaction mixture was stirred at 80° C. for 1 h. The solvent was evaporated and the crude N4-ethyl-N2-(4-(2-methyl-1H-imidazol-1-yl)phenyl)-N4-((tetrahydrofuran-2-yl)methyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-2,4-diamine (190 mg, 92%) was used as such in the next step.
