실험 절차

To a solution of tert-butyl 2-hydroxypropylcarbamate (14.3 g, 81.7 mmol) and Et3N (35.6 mL, 245.1 mmol) in CH2Cl2 (250 mL) at 0° C. was slowly added a solution of methanesulfonyl chloride (9.5 mL, 122.6 mmol) in CH2Cl2 (250 mL). The mixture was stirred at 0° C. for 2 h, diluted with CH2Cl2 (300 mL) and washed with water, 1N HCl, 5% aqueous NaHCO3 and brine. The organic layer was dried over MgSO4 and concentrated under reduced pressure to afford 1-(tert-butoxycarbonylamino)propan-2-yl methanesulfonate (19.5 g, 94%) as a light yellow oil. Mass calculated for C9H19NO5S=253.32; found: [M+H]+=254.2.
