Versuchsvorschrift

A mixture of 0.59 ml of 1,1,1,3,3,3-hexamethyldisilazane and 45 mg of methanol was added to a solution of 150 mg of 3-[1-(tert.butoxy-carbonyl)-1',3'-dihydrospiro[pyrrolidine-3,2'-pyrrolo[1,2-a]indol]-9'-yl]-4-(1-methyl-3-indolyl)-furan-2,5-dione in 10 ml of DMF and stirred for 72 hours. The solvent was removed by evaporation and the residue was treated with 10 ml of methanol. After evaporation, the residue was subjected to chromatography on silica gel using dichloromethane/ethyl acetate (4:1) for the elution. There were obtained 120 mg of 3-[1-(tert.butoxycarbonyl)-1',3'-dihydrospiro[pyrrolidine-3,2'-pyrrolo[1,2-a]indol]-9'-yl]-4-(1-methyl-3-indolyl)-1H-pyrrole-2,5-dione of melting point 232°-235° C.
