3,3-Diphenylpropionic acid (I) was treated with SOCl2 to give acid chloride (II) and then converted to amide (III) using liquid ammonia. Dehydration of (III) with P2O5 led to diphenylpropionitrile (IV), which was treated with ammonia in methanol to afford the iminoester (V). The condensation of (V) with 2-oxo-4-phthalimido-1-butyl acetate (VI) in liquid ammonia furnished imidazole (VII). Finally, deprotection of the phthaloyl group of (VII) with methanolic hydrazine afforded the title compound.
