Versuchsvorschrift

The mixture of (2S)-2-[(tert-butoxycarbonyl)amino]-2-phenylethyl 4-methylbenzenesulfonate (350 mg, 0.9 mmol, 1.0 eq.) and sodium azide (117 mg, 1.8 mmol, 2.0 eq.) in N,N-dimethylformamide (5 ml) was stirred at 65° C. overnight. The mixture was cooled to room temperature and diluted with water and ethyl acetate. The organic layer was separated and washed with brine, dried, and concentrated to afford tert-butyl [(1S)-2-azido-1-phenylethyl]carbamate in 90% yield.
