反应详情

10.8 g of benzyl 3-pyridyl ketone are stirred together with 40 ml of pyridine and a solution of 8 g of hydroxylamine hydrochloride in 15 ml of pyridine for 6 hours at 100°. The reaction mixture is poured onto ice/water and the resulting mixture is stirred for a further 15 minutes. The crystals which have precipitated are filtered off with suction, washed with water and dried under a high vacuum. Benzyl 3-pyridyl ketone oxime with a melting point of 122°-126° is obtained.
