실험 절차

To a solution of trans-3-((tert-butoxycarbonyl)amino)cyclobutyl methanesulfonate (29 g, 109 mmol) in DMF (100 mL) was added sodium azide (5.68 mL, 162 mmol, Sigma-Aldrich Chemical Company, Inc.) portionwise and the mixture stirred at 85° C. for 18 h. The reaction was diluted with water (200 mL) after cooling and extracted with EtOAc (3×100 mL). The combined organic was washed with water (2×100 mL) and brine, dried over Na2SO4 and evaporated in vacuo to give product tert-butyl(cis-3-azidocyclobutyl)carbamate (22 g, 104 mmol, 95% yield) that was used in the next step without further purification.
