YieldReaction ConditionsOperation in experiment
100% With N-ethyl-N,N-diisopropylamine; at 20℃; for 0.25h; Ethyl oxalyl chloride (44 mL, 390 mmol) was added to a solution of <strong>[168268-00-6]4-benzyloxy-3-fluoroaniline</strong> (44 g, 180 mmol) in diisopropylethylamine (69 mL, 400 mmol) and stirred at room temperature for 15 min. The mixture was extracted with dichloromethane and washed with water and brine. The organic layer was dried over sodium sulfate and concentrated to afford ethyl [(4- benzyloxy-3-fluorophenyl)amino](oxo)acetate (58.4 g, 100 %). 1H NMR (400 MHz, J6- DMSO): delta 10.87 (s, IH), 7.73 (d, IH), 7.69 (d, IH), 7.53 (d, IH), 7.46-7.40 (m, 4H), 5.17 (s, 2H), 4.31 (q, 2H), 1.31(t, 3H); IR (cm"1): 1732, 1705, 1558, 154I, 1508, 1456, 1273, 1186, 1167, HOl, 999, 858, 741, 694; LC/MS (M+H = 318).
