実験手順

A solution of 2.0 g (5 mmol) 6,7,12,13-tetrahydro-3,9-dimethoxy-6-methyl-5,7-dioxo-5H-indolo[2,3-a]-pyrrolo[3,4-c]carbazole in 100 ml dry dimethylformamide is added dropwise at 20° C. to a suspension of 182 mg (6.1 mmol) sodium hydride (80% in paraffin oil) in 5 ml dimethylformamide. After stirring for 1 hour at 20° C. 738 mg (6.1 mmol) 3-dimethylaminopropyl chloride are added thereto and the reaction mixture is stirred for 20 hours at 20° C. The solvent is distilled off in a vacuum, the residue is mixed with 150 ml ethyl acetate and 150 ml of water and the solid material insoluble in both phases is filtered off. The solid material is taken up in tetrahydrofuran, the tetrahydrofuran solution is washed with a saturated sodium chloride solution, dried over anhydrous sodium sulphate, filtered and evaporated. The residue, together with the residue from the ethyl acetate solution, is chromatographed on silica gel with ethyl acetate/methanol (4:1 v/v). The fraction with the Rf 0.2 in ethyl acetate/methanol (3:1 v/v) is isolated and stirred with diisopropyl ether/ethyl acetate (9:1 v/v). The crystals formed are filtered off. 12-(3-Dimethylaminopropyl)-6,7,12,13-tetrahydro-3,9-dimethoxy-6-methyl-5,7-dioxo-5H-indolo-[2,3-a]pyrrolo[3,4-c]carbazole is obtained in the form of yellow-brown crystals.
