Various substituted ethyl 1-(2-nitrophenyl)-3-methylindole-2-carboxylates (II) on catalitic hydrogenation over Raney-nickel at 60 psi undergo reductive cyclisation to afford 12-methyl-1-oxo-1,2-dihydroquinoxalinoindole (III) and not ethyl 1-(2-aminophenyl)-3-methylindole-2-carboxylate.III on LAH reduction affords 12-methyl-1,2-dihydroquinoxalinoindole (IV).The structures of the compounds are confirmed by their IR and PMR data.
