실험 절차

tert-Butyl 2-(4-(2-methyl-1H-imidazol-1-yl)phenylamino)-4-(trifluoromethylsulfonyloxy)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (250 mg, 0.45 mmol, example 69c) was dissolved in DMF (2 mL). 4-Aminomethyltetrahydropyran (51.9 mg, 0.45 mmol) was added and the reaction mixture was stirred at 85° C. overnight. The reaction was allowed to reach room temperature and the solvent was evaporated under reduced pressure. The crude was purified by flash column chromatography using dichloromethane and methanol as eluent yielding tert-butyl 2-(4-(2-methyl-1H-imidazol-1-yl)phenylamino)-4-((tetrahydro-2H-pyran-4-yl)methylamino)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (62.0 mg, 26.5%). MS (ES+) m/z 520.4 (M+H)+
