実験手順
To a solution NaH (0.29 g, 7.35 mmol) in DMF (10 mL) was added a solution of (S)-tert-butyl 1-azido-3-(benzyloxy)propan-2-ylcarbamate (1.5 g, 4.9 mmol) in DMF (10.0 mL). The mixture was stirred at RT for 30 min followed by addition of MeI (1.0 mL, 9.8 mmol). The resulting mixture was stirred for another 2 h. LCMS indicated the completion of the reaction. The mixture was quenched with saturated NH4Cl solution and extracted with EtOAc (200 mL×2). The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure to give (S)-tert-butyl 1-azido-3-(benzyloxy)propan-2-yl(methyl)carbamate (1.8 g, crude), which was used without purification.
