실험 절차

To a mixture of 1-(3-nitrophenyl)-5-oxopyrrolidine-3-carboxylic acid (5 g, 0.02 mol), ethyl 3-amino-3-pyridylpropanoate (HCl salt) (0.03 mol) and HOAt (0.02 mol) in DMF (80 mL) at 0° C. was added i-Pr2NEt (0.03 mol), followed by 1-(3-dimethylaminopropyl)-3-ethyl carbodiimide hydrochloride (EDCI) (0.04 mol), in portions. The reaction mixture was then warmed up to room temperature and stirred overnight. The reaction solution was diluted with EtOAc (150 mL) and the organic phase was washed with saturated NaHCO3 and NaCl aqueous solution. The organic layer was dried over Na2SO4, concentrated in vacuo. The crude product was purified by flash column with 10% MeOH/EtOAc as eluent. Yellow solid was obtained. MS (ES+): 427.5 (M+H)+.
