Reaction Steps
100 mg of the product of Example 58 in 10 ml of DMSO were treated with 120 mg of 5-mercapto-1-methyltetrazole sodium salt. The solution was heated at 55° C. for 6 hours, then cooled and poured into water. The aqueous phase was extracted with ethyl acetate. The ethyl acetate extracts were dried and concentrated. Chromatography on silica gel with dichloromethane/ethyl acetate (4:1) gave 48 mg of 3-(1-methyl-3-indolyl)-4-[1-[3-(1-methyl-5-tetrazolylthio)propyl]-3-indolyl]-1H-pyrrole-2,5-dione, m.p. 95°-97° C.
