Participants

Reaction Steps

A solution of 72 mg of 3-(6,7,8,9-tetrahydropyrido[1,2-a]indol-10-yl)-4-(1-methyl-3-indolyl)furan-2,5-dione in 5 ml of dimethylformamide and 5 ml of 33% aqueous ammonia was heated to 140° C. for 4 hours. The resulting crystals were filtered off and dried to give 50 mg of 3-(6,7,8,9-tetrahydro-pyrido[1,2-a]indol-10-yl)-4-(1-methyl-3-indolyl)-1H-pyrrole-2,5-dione of melting point 286°-289° C.
