Versuchsvorschrift
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.
