Procedure
A solution of tert-butyl [3-(hydroxymethyl)phenyl]carbamate (0.6 g, 2.7 mmol) [J. Med. Chem. 1989, 32, 807-826] in dichloromethane (8.4 mL) at −10° C. was treated with N,N-diisopropylethylamine (0.7 mL, 4.0 mmol) followed by methanesulfonyl chloride (0.31 mL, 4.0 mmol and stirred at −10° C. for 1 h. The reaction mixture was quenched with water (50 mL) and extracted with dichloromethane (100 mL). The organic layer was separated, dried over anhydrous sodium sulfate, filtered, and evaporated to give the desired product as a crude yellow oil that was used without further purification. LCMS for C13H19NO5SNa (M+Na)+: m/z=323.9.
