合成路线1

The reductive condensation of N-Boc-L-isoleucinal (I) with glycine methyl ester (II) using sodium triacetoxyborohydride afforded secondary amine (III), which was further reductively condensed with 1-naphthaldehyde (IV), yielding tertiary amine (V). After basic hydrolysis of the methyl ester group of (V), the resulting carboxylic acid (VI) was coupled with L-methionine methyl ester (VII) by means of EDC and HOBt to give peptide (VIII). Subsequent deprotection of the Boc group of (VIII) with HCl in cold EtOAc furnished the required intermediate (IX).

合成路线2

Protection of 4-imidazoleacetic acid methyl ester (X) with triphenylmethyl bromide provided the N1-trityl derivative (XI). Subsequent alkylation with 4-cyanobenzyl bromide (XII) resulted in the formation of the imidazolium salt (XIII). Deprotection of the trityl group of (XIII) was achieved upon refluxingin MeOH to give (XIV). Hydrolysis of the methyl ester group of (XIV) under either acidic or basic conditions yielded imidazoleacetic acid (XV). This was finally coupled with the intermediate amine (IX) using EDC and 3-hydroxy-1,2,3-benzotriazin-4-one (HOOBT) to provide the title compound.
