Procedure

A mixture of 51 g (0.25 mole) of 5-(p-chlorophenyl)-2-furonitrile, 19 g (0.27 mole) of hydroxylamine hydrochloride, 18 g (0.27 mole) of potassium hydroxide and 750 ml of absolute ethanol was heated under reflux for 1 hour. The reaction mixture was concentrated on a rotary evaporator and cooled in ice overnight. The solid was collected by filtration and washed with anhydrous ether to give 43 g (73%). Two recrystallizations from absolute ethanol gave an analytical sample, m.p. 167°-169°.
