Alkylation of 4-nitroimidazole (XII) by means of ethyl bromoacetate (XIII) gave ethyl 2-(4-nitro-1-imidazolyl)acetate (XIV). Reduction of (XIV) to the corresponding amine (XV) was effected by catalytic hydrogenation over Pd/C. Coupling of (XV) with dipeptide (XI) gave (XVI), which was hydrolyzed to carboxylic acid (XVII) using LiOH. This was finally coupled with proline amide (XIX), (obtained by treatment of L-proline (XVIII) with benzylamine and CDI), to furnish the title compound.
