Reaction Steps
56 mg of 3-(1-methyl-3-indolyl)-4-(1-naphthyl)furan-2,5-dione were treated with 5 ml of DMF and 5 ml of 33% aqueous ammonia and the mixture was heated at 130° C. for 5 hours. The formed precipitate was filtered off, washed with water and dried to give 53 mg of 3-(1-methyl-3-indolyl)-4-(1-naphthyl)-1H-pyrrole-2,5-dione, m.p. 258°-260° C.
