Triethylamine → 2-Phenoxyethyl methanesulfonate

참여 물질

반응 단계

To a solution of 2-(phenoxy)ethanol (1.35 g, 9.78 mmoles) and triethylamine (2.04 ml, 14.7 mmoles) in methylene chloride (30 ml) was added methanesulfonyl chloride (0.91 ml, 12 mmoles) with stirring under ice-cooling and the mixture was further stirred under ice-cooling for 10 minutes. The reaction solution was washed with water and the aqueous layer was extracted with methylene chloride (30 ml×3). The methylene chloride layers were combined and dried over anhydrous magnesium sulfate. After the solvent was distilled off, the residue was subjected to column chromatography [eluent: hexane/methyl (1:1)] to obtain crude 1-methanesulfonyloxy-2-(phenoxy)ethane as a pale yellow oily product.
