Versuchsvorschrift
To a 2-(benzyloxy)ethanesulfonic acid (4.0 g) was added thionyl chloride (13.5 ml) dropwise at ambient temperature for 15 minutes and the mixture was stirred at the same temperature for 10 minutes. To the mixture was added dropwise N,N-dimethylformamide (0.072 ml) at ambient temperature. The mixture was stirred at the same temperature for 20 minutes and refluxed for 1 hour. After cooling down to room temperature, the mixture was evaporated under reduced pressure to give 2-(benzyloxy)ethanesulfonyl chloride (4.1 g).
