Condensation of N-(tert-butoxycarbonyl)phenylalanine (I) with phenyllithium furnished ketone (II). The N-Boc group of (II) was deprotected with HCl in dioxan to yield aminoketone (III), which was then condensed with the succinate building block (IV) in DMF to afford succinamide (V). Further deprotection of the tert-butyl ester of (V) by treatment with trifluoroacetic acid provided carboxylic acid (VI), which was coupled with O-tert-butyldimethylsilyl hydroxylamine (VII) in the presence of EDC and HOBt to yield, after desilylation, the target hydroxamic acid.
