Procedure

850 mg of 2-isopropenyl-1-methylindole and 980 mg of N-benzylmaleimide were stirred at 110° C. for 30 minutes. The resulting solid was recrystallized from 10 ml of ethanol to obtain 1.22 g (yield: 69%) of N-benzyl-1-methyl-9-methyl-1,2,3,4-tetrahydrocarbazole-3,4-dicarboximide as colorless needles.
