Procedure

A mixture of 100 mg of 3-[1-(3-aminopropyl)-3-indolyl]-4-(1-methyl-3-indolyl)-1H-pyrrole-2,5-dione acetate, containing an extra equivalent of acetic acid, 75 mg of 2-chloropyrimidine and 100 mg of sodium carbonate in 100 ml of DMSO was heated at 80° C. for 2 hours. 50 ml of water were added to the cooled solution and the precipitate was filtered off and chromatographed on silica gel with 5% methanol in dichloromethane to give 60 mg of 3-(1-methyl-3-indolyl)-4-[1-[3-(2-pyrimidinylamino)propyl]-3-indolyl]-1H-pyrrole-2,5-dione, m.p. 214°-215° C.
