((2-Chloroethyl)sulphonyl)benzene → HCID 20277899, compound

Participants

Reaction Steps

A solution of methallylamine (8.0 g; 1.12 mol), in toluene (20 ml) was added dropwise to a solution of 1-chloro-2-phenylsulphonylethane (11.54 g; 56.4 mmol) in toluene (100 ml) at 0° C. When the addition was complete the reaction mixture was allowed to warm to room temperature and stirred for 1 hr. Thin layer chromatography indicated that all of the starting material had been consumed. Ether (150 ml) was added and the precipitate filtered off. Removal of the solvent from the filtrate produced a colourless oil which was subjected to silica gel column chromatography using ethyl acetate as eluent. Fractions containing the component Rf=0.37 (ethyl acetate) were combined and evaporated to give the title amine as a colourless oil, in 75% yield.
