実験手順
To a stirred solution containing the above 4-N,N-dimethylamino-6-aminoquinazoline (0.65 g, 3.45 mmol), acrylic acid (4 mol eq., 13.8 mmol, 0.95 mL), and pyridine (excess, 1.3 mL) in DMA (20 mL) under N2 was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCI.HCl) (2 mol eq., 6.90 mmol, 1.32 g). The standard procedure above was followed to give after chromatography on silica gel eluting with EtOAc/CH2Cl2 (1:1) to MeOH/CH2Cl2/EtOAc (1:4:5), [4-(N,N-dimethylamino)quinazolin-6-yl]acrylamide (350 mg, 42%) as a cream powder, mp (CH2Cl2/hexane) 204-206° C.
