该中间体在本合成路线中的序号:(VI)

2,4-Dichlorobenzoic acid (V) was converted to acid chloride (VI) using SOCl2. Further Friedel-Crafts condensation of (VI) with toluene in the presence of AlCl3 produced benzophenone (VII). Benzylic bromination of (VII) with N-bromosuccinimide gave bromide (VIII). Finally, displacement of the bromine of (VIII) by means of amine (IV) furnished the title compound.

Acylation of L-phenylalanine tert-butyl ester (I) with 2,4-dichlorobenzoyl chloride (II) provides the corresponding amide (III). This is then N-alkylated with 3-nitrobenzyl bromide (IV) in the presence of NaH to yield (V). The tert-butyl ester group of (V) is finally cleaved with trifluoroacetic acid to furnish the target carboxylic acid. (1-3)
