Reaction Steps

180.5 mg of BE-13793C (12,13-dihydro-1,11-dihydroxy-5H-indolo[2,3-a]pyrrolo[3,4-c]carbazole-5,7-(6H)-dione) was dissolved in 137 ml of N,N-dimethylformamide (DMF), 510 mg of potassium carbonate was added, and 170 μl of benzyl bromide was added under ice cooling. The reaction solution was stirred at room temperature for 2 hours and, after addition of 200 ml of water, extracted with 200 ml of ethyl acetate, and the extract was dried over sodium sulfate and concentrated under reduced pressure to give 1,11-dibenzyloxy-12,13-dihydro-5H-indolo[ 2,3-a]pyrrolo[3,4-c]carbazole-5,7(6H)-dione (yield: 93.7%).
