Procedure

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) was dissolved in DMF (2 mL). Cyclohexanamine (44.7 mg, 0.45 mmol) was added and the reaction mixture was heated at 85° C. overnight. The reaction mixture was allowed to reach room temperature, the solvent was evaporated under reduced pressure and the crude was purified by flash chromatography using dichloromethane and methanol as eluent yielding tert-butyl 4-(cyclohexylamino)-2-(4-(2-methyl-1H-imidazol-1-yl)phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (124 mg, 54.6%).
