실험 절차
To a mixture of (+)-carbobenzyloxy-D-proline (1.5 g, 6 mmol), EDAC (2.3 g, 2 eq.), HOBt (0.8 g, 2 eq.) in DMF (20 mL) was added triethylamine (1.5 mL) and cyclopropylamine (0.8 mL, 2 eq.). After stirring at RT for 18 h, the reaction was basified with sodium bicarbonate, poured to brine, and followed by extraction with dichloromethane. After concentration of the combined extracts, the residue was purified on a silica gel column eluting with 100% EtOAc to give 1.6 g (92%) of (R)-2-cyclopropylcarbamoyl-pyrrolidine-1-carboxylic acid benzyl ester.
