Reaction Steps

0.28 g of 3-(1-methyl-3-indolyl)-4-(3-thienyl)furan-2,5-dione was treated with 10 ml of DMF and 40 ml of 33% aqueous ammonia. The mixture was heated at 140° C. for 4 hours. The cooled solution was poured into 150 ml of water and the resulting precipitate was filtered off and dried to give 0.15 g of 3-(1-methyl-3-indolyl)-4-(3-thienyl)-1H-pyrrole-2,5-dione, m.p. 211°-212° C.
