Conditions

Temperature: 140 °C

Procedure

0.17 g of 3-(5-amino-1-methyl-3-indolyl)-4-(1-methyl-3-indolyl)furan-2,5-dione was treated with 4 ml of DMF and 30 ml of 33% aqueous ammonia and the mixture was heated at 140° C. for 4 hours. The cooled solution was filtered and the residue was washed with water to give 0.08 g of 3-(5-amino-1-methyl-3-indolyl)-4-(1-methyl-3-indolyl)-1H-pyrrole-2,5-dione, m.p. 254°-256° C.
