Procedure
25.5 g (71.9 mmol) of 3-(phenylsulfonyl)-1-propanol-4-methylbenzenesulfonate [see H. O. Fong et al., Can. J. Chem., 57, 1206 (1979)]were dissolved in 45 ml of methylamine and stirred for 24 hours at 80° and 1000 kpa. Thereafter, the methylamine was evaporated under reduced pressure, the residue was poured into ice-water and extracted with methylene chloride. The methylene chloride extracts were dried over potassium carbonate and evaporated under reduced pressure, whereby there were obtained 14.1 g of N-methyl-3-(phenylsulfonyl)propylamine as an oil, MS: 214 (M+H)+.
