Protection of 4-imidazoleacetic acid methyl ester (X) with triphenylmethyl bromide provided the N1-trityl derivative (XI). Subsequent alkylation of (XI) 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), which was subsequently coupled with the intermediate amine (IX) using EDC and 3-hydroxy-1,2,3-benzotriazin-4-one (HOOBT) to provide amide (XVI). Finally, saponification of the methyl ester group of (XVI) furnished the title compound.
