Reaction Steps
160 mg of 3-(1-benzothiophen-3-yl)-4-(1-methyl-3-indolyl)furan-2,5-dione were treated with 2 ml of DMF and 20 ml of 33% aqueous ammonia and the mixture was heated at 140° C. for 5 hours. The cooled mixture was filtered and the residue was washed with water and dried. The solid was purified on silica gel with 50% ethyl acetate in petroleum ether to give 20 mg of 3-(1-benzothiophen-3-yl)-4-(1-methyl-3-indolyl)-1H-pyrrole-2,5-dione, m.p. 250°-255° C.
