Benzoic acid derivative (XIII) was converted to pentafluorophenyl ester (XIV) by DCC-mediated coupling with pentafluorophenol. Then, condensation with tri-tert-butyl L-gamma-glutamyl-D-glutamate (XV) furnished the corresponding amide (XVI). The tert-butyl esters of (XVI) were finally cleaved by treatment with trifluoroacetic acid.
