실험 절차

To a stirred solution of benzyl 3-{3-[(tert-butoxycarbonyl)amino]pyridin-4-yl}-3-hydroxypyrrolidine-1-carboxylate (4.38 g, 0.0106 mol) in methylene chloride (12.00 mL, 0.1872 mol) at rt was added trifluoroacetic acid (10.00 mL, 0.1298 mol) and the reaction mixture was stirred at rt for 4 h. LCMS (m+1, 314.2) indicated that the reaction was complete. The volatiles were removed and NMR data supported the formation of the desired product.
