실험 절차

To a solution of (3S)-1-Cbz-3-[cyclohexyl (acetyloxypivaloyl)amino]pyrrolidine (1.00 g, 2.25 mmol), prepared in Step B, in dioxane (10 mL) was added portionwise Pd/C (200 mg), and the mixture was stirred for 12 h under hydrogen. The reaction solution was filtered though Celite and the filtratae concentrated to give the title compound (657 mg, 84%).
