Reaction Steps

A mixture of 8-amino-4-chloro-3-ethoxycarbonylquinoline (45 mg), triethylamine (0.026 ml) and 10%o palladium on carbon (15 mg) in dioxane was stirred for 7 hours at ambient temperature under 3 atmospheric pressure of hydrogen. Insoluble material was filtered off and the filtrate was concentrated in vacuo. The residue was purified by column chromatography on silica gel (ethyl acetate-dichloromethane) to give 8-amino-3-ethoxycarbonylquinoline (24.5 mg).
