Procedure

50 mg (0.042 mmol) of 3(RS)-[[N-[N-[N-[N-[N-[3-(tert-butoxycarbonyl)propionyl]-O-tert-butyl-L-α-aspartyl]-O-tert-butyl-L-α-glutamyl]-2-methyl-L-phenylalanyl]-3-methyl-L-valyl]-L-leucyl]amino]-5,5,5-trifluoro-2′,4′-dimethyl-2-oxovaleranilide were dissolved in 3 ml of trifluoroacetic acid and the solution was stirred at room temperature for 30 minutes. The solution was then diluted with 10 ml of toluene and the solvent was removed by evaporation. The solid was triturated with diethyl ether to give 29 mg of 3(RS)-[[N-[N-[N-[N-[N-(3-carboxypropionyl)-L-α-aspartyl]-L-α-glutamyl]-2-methyl-L-phenylalanyl]-3-methyl-L-valyl]-L-leucyl]amino]-5,5,5-trifluoro-2′,4′-dimethyl-2-oxovaleranilide as a white solid, MS: m/e 1020.4 [M+H]+.
