Reaction Steps

1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (1.79 g, 9.34 mmol) was added to a solution of 1-(quinolin-2-yl)piperidine-4-carboxylic acid hydrochloride (1.14 g, 3.89 mmol), N,N-dimethyl-4-aminopyridine (1.42 g, 11.6 mmol), and ethanol (546 μL, 9.34 mmol) in dichloromethane (20 mL), and the mixture was stirred overnight at room temperature. Then, the solvent in the reaction solution was distilled off under reduced pressure. A solution of the obtained residue in ethyl acetate was washed with water twice and brine once and dried over anhydrous sodium sulfate, and then, the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography [elute: hexane/ethyl acetate=95/5-60/40 (gradient)] to obtain the title compound (1.07 g, yield: 96%).
