Alkylation of 2-chlorobenzimidazole (VI) with iodomethane and NaOH leads to 2-chloro-1-methylbenzimidazole (VII). The 2-chloro group of (VII) is then displaced with hydrazine hydrate to afford hydrazine (VIII). Finally, condensation between ketone (V) and hydrazine (VIII) gives rise to the target hydrazone.
