Versuchsvorschrift

A solution of 7.7 g of p-toluenesulfonyl chloride in 15 ml of pyridine is added dropwise in the course of 5 minutes to a solution, which is stirred at -10°, of 8.5 g of benzyl 3-pyridyl ketone oxime in 20 ml of pyridine. The reaction mixture is placed in a refrigerator for 24 hours and then poured onto ice/water. After some stirring and grinding, the oil which has separated out solidifies to crystals. These are filtered off with suction, washed with water and dried under a high vacuum. Benzyl 3-pyridyl ketone oxime p-toluenesulfonate is obtained and this is employed in the next stage without further purification.
