2-氯-6-氟-N-羟基苯甲酰胺

反应条件: temp:72.51; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 15.6 g of 2-chloro-6-fluorobenzonitrile, 9.0 g of hydroxylamine hydrochloride, 7.4 g of sodium carbonate, 50 ml of ethanol and 15 ml of water was stirred at 70-75° C. for 16 h. The solvent was evaporated and the residue was stirred with tertbutyl methyl ether, and the filtrate afforded, after evaporation of the solvent, 17.6 g of the desired product of m.p. 115-120° C. The solvent was evaporated the residue was stirred with tertbutyl methyl ether the filtrate afforded after evaporation of the solvent, 17.6 g of the desired product of m.p. 115-120° C.
