실험 절차
To a solution of indole-3-acetic acid (248 mg, 1.42 mmol) in DMF (3 ml) was added 1,1-carbonyldiimidazole (230 mg, 1.42 mmol). After stirring for 2 h a solution of the aminopyrrolidinone of Example S (352 mg, 1.42 mmol) in DMF (1 ml) was added. After stirring for an additional 18 h the solvent was evaporated to give an oil which was chromatographed on silica gel eluting with EtOH/CH2Cl2 (2%-5%) to give 470 mg (91%) of the title compound as a solid.
