Reaction Steps

A mixture of 2-(cyclohexylamino)-6-fluoro-N-(1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)nicotinamide (150 mg), piperidine (64 mg), potassium carbonate (63 mg) and DMF was stirred at 60° C. for 18 hours. Then, water was added, followed by extraction with ethyl acetate. After drying the organic layer with magnesium sulfate, the solution was concentrated under a reduced pressure, and the residue was purified by silica gel column chromatography (basic silica gel, hexane:ethyl acetate, 2:1 to 1:1) to obtain 2-(cyclohexylamino)-N-(1-methyl-2-oxo-1,2,3,4-tetrahydroquinolin-7-yl)-6-piperidin-1-ylnicotinamide (138 mg) as a solid.
