To a solution of 2-(aminomethyl)-3-methylquinolin-4(1H)-one dihydrochloride (212 mg) in pyridine-DMF (8:1, 9 mL) was added hexanesulfonyl chloride (180 mg) under ice-cooling, and the mixture was stirred at room temperature for 12 hours. The reaction mixture was concentrated under reduced pressure, and water (50 mL) was added to the residue, followed by extraction with ethyl acetate (100 mL). The organic layer was washed sequentially with water and saturated brine, and then dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and then the residue was purified by silica gel column chromatography (eluent: chloroform/methanol=20/1) to obtain N-[(3-methyl-4-oxo-1,4-dihydroquinolin-2-yl)methyl]hexane-1-sulfonamide (56 mg).
