2-(BENZYLOXY)ETHANESULFONAMIDE

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a 28% ammonium hydroxide (10 ml) was added dropwise 2-(benzyloxy)ethanesulfonyl chloride (4.1 g) in dichloromethane (10 ml) over 10 minutes under ice-cooling. The mixture was stirred at ambient temperature overnight. The organic layer was separated and the aqueous layer was extracted with dichloromethane/methanol (5/1). The combined organic layer was dried over sodium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=50/50) to give 2-(benzyloxy)ethanesulfonamide (1.6 g). cooling The organic layer was separated the aqueous layer was extracted with dichloromethane/methanol (5/1) The combined organic layer was dried over sodium sulfate evaporated under reduced pressure The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=50/50)
