YieldReaction ConditionsOperation in experiment
77.9% A solution of 3-aminophenol (0.35 g, 3.2 mmol) in dry DMF (20 mL) was treated with potassiumtert-butoxide (0.44 g, 3.9 mmol), and the mixture was stirred at room temperature for 1 h undernitrogen atmosphere, then a solution of 6 (0.76 g, 3.4 mmol) in DMF (50 mL) and potassium carbonatewere added respectively. The mixture was heated to 80-85 C for 2 h. After the temperature was cooled to room temperature, the mixture was diluted with water (100 mL) and extracted with EtOAc(3 100 mL). The extract was washed with brine (2 100 mL), dried over anhydrous sodiumsulfate, and concentrated under reduced pressure to give light-brown solid 7a 0.74 g, yield: 77.9%,m.p. 183.5-185.0 C. 1H-NMR (400 MHz, DMSO-d6) 3.97 (s, 3H, O-CH3), 3.98 (s, 3H, O-CH3),5.28 (s, 2H, -NH2), 6.98 (dd, J = 1.6 Hz, 9.6 Hz, 1H, Ph-H-6), 7.13 (d, J = 7.6 Hz, 1H, Ph-H-4),7.23 (d, J = 1.6 Hz, 1H, Ph-H-2), 7.43 (t, J = 7.8 Hz, 1H, Ph-H-5), 7.55 (s, 1H, quinazoline H-5), 7.63 (s, 1H,quinazoline H-8), 8.56 (s, 1H, quinazoline H-2).
