Reaction Steps

2-[(4′-Phenylacetylamino-biphenyl-4-carbonyl)-amino]-pentanedioic acid di-tert-butyl ester (45 mg) was dissolved in dichloroethane (3 mL) and added to TFA (1 mL). The mixture was stirred at room temperature for 3 hrs. Reaction was complete as determined by TLC. Solvent was removed and the resulting solid was dried under vacuum overnight. N-({4′ [(phenylacetyl)amino]-1,1′-biphenyl-4-yl}carbonyl)-L-glutamic acid was obtained in 84.2% yield (30.3 mg). MS (ESI) m/z 461.
