Triethylamine → Methanesulfonic acid 2-phenyl-allyl ester

참여 물질

반응 단계

To a well stirred solution of 2-phenyl-prop-2-en-1-ol (700 mg, 5.22 mmol) in dichlorometane (10 mL) at 0° C. is added triethylamine (0.945 mL, 6.78 mmol) and methylsulfonyl chloride (0.424 mL, 5.48 mmol). The reaction is allowed to stir for 10 min, warmed to room temperature and is stirred for 30 min. The reaction is quenched by the addition of a saturated aqueous solution of ammonium chloride and extracted several times with ethyl acetate. The organic layers are combined, washed with 1 N hydrochloric acid, brine, dried over magnesium sulfate, filtered and concentrated in vacuo. The residue is purified via silica gel chromatography (10% ethyl acetate in hexanes) to yield the title compound (1.07 g, 4.95 mmol).
