YieldReaction ConditionsOperation in experiment
64% With acetic acid; for 3h;Reflux; Inert atmosphere; Bromomaleic anhydride (0.34 mL, 3.7 minol) and 4-amino-2-nitrophenol (564 mg, 3.66 minol) were dissolved in acetic acid (25 mL), and stirred at r.t. overnight. The reaction mixture was then heated to reflux for 3 hours and concentrated. Recrystallisation of theresidue from ethanol provided the title compound 27 (729 mg, 64percent) as a brown solid.Rf = 0.3 (5:1 petroleum ether:ethyl acetate); m.p. 138?140 °C; 1H NMR (500 MHz, CDCI3):oe 7.06 (1H, 5), 7.28 (1H, d, J = 9.0 Hz), 7.61 (1H, dd, J = 9.0, 2.6 Hz), 8.17 (1H, d, J =2.6 Hz), 10.63 (1H, 5); 13C NMR (125 MHz, CDCI3): oe 121.0, 122.6, 123.4, 132.1, 132.2,133.4, 135.0, 154.6, 163.8, 166.8; IR: vmax 3272, 3095, 1708, 1541, 1489, 1243, 1143,1052, 787, 718, 641, 554 cm1 HRMS-ESI: [M ?
