실험 절차
A solution of 1.6 g of 3-[1-(2-acetoxyethyl)-3-indolyl]-4-(1-methyl-3-indolyl)furan-2,5-dione in 4 ml of DMF and 8 ml of 33% aqueous ammonia was heated to 160° C. for 4 hours. The precipitate was filtered off and dried to give 1.04 g of 3-[1-(2-hydroxyethyl)-3-indolyl]-4-(1-methyl-3-indolyl)-1H-pyrrole-2,5-dione, m.p. 250°-252° C.
