the bicyclic derivatives 25a–c, while its reaction with oxalyl chloride, dichloro and tetrachlorobenzoquinone derivatives, and/or dichloronaphthoquinone gave the imidazopyridine derivatives 26-29. Reaction of compound 29 with o-phenylenediamine in 1:2 ratio afforded the di-condenesed product 30 while, reaction of compound 1 with dichlororeagents in 1:2 ratio gave the polyalkyl derivatives 31a-b.
