실험 절차

To a stirred solution of 7-amino-4-[(3-bromophenyl)amino]pyrido[4,3-d]pyrimidine (J Med Chem, 1995;38:3780) (140 mg, 0.46 mmol), DMAP (14 mg) and Et3N (excess, 2.0 mL) at 0° C. under N2 was added acryloyl chloride (4.8 mol eq., 182 μL) dropwise over 4 hours. The reaction was then stirred at 20° C. diluted with water and extracted with EtOAc. The combined organic extracts were washed with brine, dried over anhydrous Na2SO4 and concentrated under reduced pressure before being chromatographed on silica gel eluting with MeOH/CH2Cl2/EtOAc (5:45:50), to give N-[4-[(3-bromophenyl)amino]pyrido[4,3-d]pyrimidin-7-yl]-acrylamide (12 mg, 7%) as a cream powder, mp (CH2Cl2/hexane) 215-220° C. (dec).
