실험 절차

To a cold (0° C.) solution of N-(tert-butoxycarbonyl)-L-leucyl-(5R)-5-ethynyl-L-proline (2.83 mmol) and N-methyl morpholine (0.39 mL, 3.50 mmol) in THF (15 mL) was added isobutyl chloroformate (0.42 mL, 3.25 mmol). The resulting cloudy white mixture was stirred at 0° C. for 30 minutes followed by the addition of a solution of ammonia (0.5 M in dioxane, 10.0 mL, 5.0 mmol). The solution was allowed to warm to room temperature and stirred for 16 hours. The reaction mixture was diluted by the addition of 1 M HCl (100 mL), and extracted with ethyl acetate (3×100 mL). The combined organic layers were dried (sodium sulfate), filtered, and concentrated to provide the titled compound.
