실험 절차

To a solution of 6-amino-4-[(3-bromophenyl)amino]pyrido[3,4-d]pyrimidine (J Med Chem, 1996;39:1823) (250 mg, 0.82 mmol), Et3N (excess, 2.0 mL) and DMAP (catalytic) in THF (30 mL) under nitrogen was added methacryloyl chloride (3×1.1 mol eq., total of 264 μL), the reaction conditions and work up were followed as above to give after column and preparative layer chromatography on silica gel eluting with EtOAc/CH2Cl2 (1:1), N-[4-[(3-bromophenyl)amino]pyrido-[3,4-d]pyrimidin-6-yl]-2-methylacrylamide (18 mg, 6%) as a cream powder, mp (CH2Cl2/hexane) 177-178° C.
