Reaction Steps
Methanesulfonyl chloride (0.60 mL, 7.76 mmol) was added to a solution of (2-hydroxy-ethyl)-carbamic acid tert-butyl ester (1.04 g, 6.46 mmol) and triethylamine (1.35 mL, 9.70 mmol) in dichloromethane (35 mL) cooled to 0° C. The solution was stirred for one hour, after which time it was diluted with ethyl acetate, washed with saturated NaHCO3 (2×), brine, dried over Na2SO4 and concentrated to a thick colorless liquid (1.37 g, 89%).
