Popov, I. I. published the artcileReaction of 2-(chloromethyl)benzimidazoles with acetylacetone and benzoylacetone. Acidic cleavage of substituted β-diketones, Recommanded Product: 2-(Chloromethyl)-1-methyl-1H-benzo[d]imidazole, the publication is Khimiya Geterotsiklicheskikh Soedinenii (1996), 1067-1071, database is CAplus.
The title reactions gave benzimidazolyl ketones I (R = R1 = Me; R = Ph, R1 = H, Me). When 2-(chloromethyl)benzimidazole reacted with acetylacetone, the product was the pyrrolobenzimidazole II.
