Reaction Steps
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). (R)-(tetrahydrofuran-2-yl)methanamine (45.6 mg, 0.45 mmol) was added and the reaction mixture was stirred overnight at 85° C. The solvent was evaporated under reduced pressure and the crude crude was purified by flash column chromatography using dichloromethane and methanol as eluent and gave (R)-tert-butyl 2-(4-(2-methyl-1H-imidazol-1-yl)phenylamino)-4-((tetrahydrofuran-2-yl)methylamino)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (75 mg, 33%). MS (ES+) m/z 506.4 (M+H)+
