Procedure

To a stirring solution of tert-butyl 3-hydroxypropylcarbamate (431 mg) at 0° C. in dichloromethane, triethylamine (686 μL) was added, followed by methanesulfonyl chloride (209 μL). The reaction was stirred for 15 minutes, then allowed to warm to room temperature and stir for 1 hour more. Additional triethylamine (686 μL) and methanesulfonyl chloride (209 μL) were added. One hour later the reaction was diluted with EtOAc and washed with saturated NaHCO3 and brine. The solution was dried over Na2SO4 and concentrated in vacuo to give the titled compound. ESI+ MS: 259 [M+H]+.
