2-tetralinol (0.86 g) in pyridine (5 ml) was stirred with cooling to 0°. Methylsulphonyl chloride (0.8 g) was added dropwise while maintaining the temperature at 0°. The mixture was then allowed to warm to room temperature and was stirred for 0.5 hour. The mixture was then poured on to ice and immediately a white precipitate formed; the mixture was allowed to stand overnight. The precipitate was then filtered off, washed with water and air-dried to give 2-methylsulphonyloxytetralin (0.72 g), m.p. 60°-62°.
