Reaction Steps

Sodium bicarbonate (500 mg) and palladium-on-charcoal are successively added to a solution of 9-methoxy-1-ethyl-2,3,4,6,7,12-hexahydroindolo[2,3-a]quinolizin-4-one (500 mg) in ethanol. and the mixture is stirred overnight under a hydrogen atmosphere. After filtration and evaporation of the solvent, the crude product is recrystallized from ethyl acetate. 9-Methoxy-I-ethyl-1,2,3 ,4,6,7,12,12b-octahydroindolo[2,3-a]quinolizin-4-one is thus recovered (76%).
