Procedure

A solution of 2-[(Biphenyl-4-carbonyl)-amino]-pentanedioic acid 1-tert-butyl ester 5-methyl ester (1.5 g, 3.8 mmol) in dichloroethane (26 mL) was added to TFA (13 mL) at room temperature. The mixture was stirred for 4 hrs. and TLC indicated the reaction was complete. Solvent was removed by rotovap. The solid thus obtained was dried under vacuum to provide 1.128 g of 2-[(Biphenyl-4-carbonyl)-amino]-pentanedioic acid 5-methyl ester [G9591-161-1] in 87% yield. MS (ESI) m/z 342.
