Reaction Steps

2 g of ethyl 2-fluoro-7a,8,9,10,11,11a-hexahydro-4-oxo-4H-pyrido[3,2,1-jk]carbazol-5-carboxylate was dissolved in 80 ml of methanol, and 5 ml of hydrazine hydrate was added thereto. The mixture was then heated while refluxing. The precipitated yellow needle crystals were separated by filtration, and recrystallized from ethanol to obtain 1.7 g of 2-fluoro-7a,8,9,10,11,11a-hexahydro-4-oxo-4H-pyrido[3,2,1-jk]carbazol-5-carbohydrazide monohydrate.
