Reaction Steps

10 g (0.042 mole) of tetralone-1-oxime are dissolved in 80 ml of anhydrous pyridine. 10.8 g of benzenesulfonic acid chloride are added dropwise in the course of 15 minutes at room temperature and the solution is left to stand for 12 hours. 5 ml of water are then added, after which the solution is poured into 300 ml of ice-cold 4 N HCl. The resulting precipitate is filtered off, dried and recrystallized from ethanol. 13.6 g (92.8% yield) of 5-methoxy-tetralone-1-oxime benzenesulfonate, of melting point 142°-144° C., are isolated.
