반응 단계
To a stirred solution of the above 6-aminoquinazoline (276 mg, 0.64 mmol), acrylic acid (6 mol eq., 3.85 mmol, 264 mL), and Et3N (excess, 1.0 mL) in DMA (10 mL) under N2 was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCI.HCl) (3 mol eq., 1.92 mmol, 369 mg). The standard procedure above was followed to give after chromatography on grade III alumina eluting with EtOAc/hexane (1:1) to MeOH/EtOAc (3:97), N-[4-[(3-bromophenyl)amino]-7-[4-(N,N-dimethylamino)butyloxy]-quinazolin-6-yl]acrylamide (98 mg, 32%) as a cream powder, mp (CH2Cl2/Et2O) 112-115° C.
