tert-Butyl 2-(4-(1-methyl-1H-pyrazol-4-yl)phenylamino)-4-(trifluoromethylsulfonyloxy)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (1 g, 1.80 mmol) and 2-(phenylamino)ethanol (0.228 mL, 1.80 mmol) in dimethylsulfoxide (3 mL) were charged in a thick wall glass, which was sealed and heated under microwave irradiation at 70° C. for 7 h. The solvent was evaporated together with toluene, the crude impregnated in silica gel and purified by flash chromatography (ISCO) using dichloromethane/methanol (0-10%) as eluent and the solvent evaporated under reduced pressure yielding tert-butyl 4-((2-hydroxyethyl)(phenyl)amino)-2-(4-(1-methyl-1H-pyrazol-4-yl)phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidine-6(5H)-carboxylate (0.882 g, 90%).
