실험 절차

A solution of 5-(tert-butoxycarbonylamino)-tetrahydro-2H-pyran-3-yl methanesulfonate (90 mg, 0.3 mmol) and sodium azide (30 mg, 0.5 mmol) in 10 mL of dry N,N-dimethylformamide was heated to 100° C. for 3 h. The reaction mixture was cooled to room temperature, 40 mL of water were added, product extracted with ethyl acetate (2×50 mL), organics combined dried with sodium sulfate, filtered and concentrated to give tert-butyl 5-azido-tetrahydro-2H-pyran-3-ylcarbamate (100 mg, crude) which was used directly in the next step without further purification.
