Synthesis and reactivity of 2-(2-furyl)-1,7-dimethyl-1H,7H-benzo[1,2-d: 3,4-d′]diimidazole

2-(2-Furyl)-1,7-dimethyl-1 H ,7 H -benzo[1,2- d : 3,4- d ′]diimidazole was synthesized by the Weidenhagen reaction followed by N-methylation. Electrophilic substitution reactions of the title compound (nitration, bromination, sulfonation, formylation, and acylation) involved both the furan ring and central benzene fragment.
