Reaction Steps

To a stirred mixture of 8-nitro-4-methylquinoline (250 mg), ferric chloride hexahydrate (7.18 mg) and activated carbon (38 mg) in methanol was added hydrazine monohydrate (266 mg) at 65° C., and the mixture was stirred for 1 hour at the same temperature. Insoluble material was filtered off, and the filtrate was concentrated in vacuo The mixture was dissolved in ethyl acetate, washed with brine, dried over magnesium sulfate and evaporated in vacuo to give 8-amino-4-methylquinoline (208.8 mg).
