The reaction of ethyl valerimidate hydrochloride (I) with cyanamide in ethanol yielded cyanoimidate (II), which was converted into the cyanoimidoylglycine (IV) on treatment with glycine ethyl ester (III) and triethylamine. Alkylation of (IV) with the biphenyl derivative (V) in the presence of 1 mole of NaH in DMF gave the intermediate cyanoamidine (VI), which, by further addition of half an equivalent of sodium hydride was cyclized to the imidazole (VII). Acylation of (VII) with 3,3-dimethylacryloyl chloride (VIII) in cold pyridine yielded amide (IX), and then N-alkylation with iodomethane and sodium hydride in DMF provided (X). Acidic treatment with acetic acid in refluxing ethanol removed the trityl group to give (XI).
