실험 절차

2-[(Biphenyl-4-carbonyl)-amino]-pentanedioic acid 1-tert-butyl ester 5-methyl ester (1.5 g, 3.8 mmol) was dissolved in dichloroethane (26 mL) and the mixture was added to TFA (13 mL). The mixture was stirred at room temperature for 4 hrs. TLC indicated the reaction was complete. Solvent was evaporated by rotovap. The solid obtained was washed with EtOAc and water. After drying, 2-[(Biphenyl-4-carbonyl)-amino]-pentanedioic acid 5-methyl ester was obtained in 87% yield (1.128 g). MS (ESI) m/z 342.
