Popov, I. I. published the artcileTransformations of 2-(α-chloroalkyl)benzimidazoles, Recommanded Product: 2-(Chloromethyl)-1-methyl-1H-benzo[d]imidazole, the publication is Khimiya Geterotsiklicheskikh Soedinenii (1993), 664-72, database is CAplus.
Phase-transfer dehydrochlorination/cyclodimerization of title compounds I (X = Cl: R = H, Me) in water-DMSO system afforded pyrazinobis(benzimidazole)s II in 96 and 93% yields, resp. II (R = Me) was similarly obtained (in 76% yield) via dehydration/cyclodimerization of I (X = OH, R = Me) in polyphosphoric or sulfuric acid; I (X = OH, R = H) was inert under the reaction conditions. II (R = H) was obtained in 90% yield via diazotization of I (X = NH2, R = H). Phase-transfer dehydrochlorination of (chloromethyl)benzimidazole III using DMF or EtOH afforded the corresponding carbene-derived products IV (R1 = NMe2, OEt, resp.). Phase-transfer dehydrochlorination of (chloromethyl)benzimidazoles (using DMSO) in presence of β-diketones MeCOCH2COR (R = Me, Ph) afforded pyrrolobenzimidazoles V (R1 = H, Me).
