실험 절차

To a solution of (1R,2R)-N-(benzyloxycarbonyl)-1-(hydroxymethyl)-2-(tert-butoxy)propanamine (1.6 g, 5.4 mmol) in anh. pyridine (30 mL) at 4° C. was added methanesulfonyl chloride (0.75 mL, 9.7 mmol) dropwise. The reaction was stirred for 5.5 h, then was diluted with EtOAc (200 mL) and washed with a 1N HCl solution (4×200 mL). The combined organic layers were dried (MgSO4) and concentrated under reduced pressure to yield (1R,2R)-N-(benzyloxycarbonyl)-1-(methanesulfonyloxymethyl)-2-(tert-butoxy)propanamine as an oil (2.03 g, 100%): TLC (25% EtOAc/hex) Rf0.31.
