Reaction Steps

To a solution of 8-hydroxyimino-5,6,7,8-tetrahydroisoquinoline (960 mg) and p-toluenesulfonyl chloride (1.69 g) in acetone was added 1N sodium hydroxide (8.88 ml) and the mixture was heated at 55° C. for 2 hours. The acetone was evaporated and the aqueous reaction mixture was extracted with ethyl acetate. The extract was washed with brine and dried over sodium sulfate and concentrated in vacuo to give 8-(4-methylphenylsulfonyl)oxyimino-5,6,7,8-tetrahydroisoquinoline (1.25 g).
