4-(2-Quinolylmethylene)piperidine (9.62 g) was dissolved in ethanol (500 ml), and 10% palladium-carbon (1.9 g) was added to the solution. The mixture was stirred under a hydrogen stream at room temperature for 90 minutes. After removal of the catalyst by filtration, the filtrate was concentrated under reduced pressure, to thereby obtain the title compound as a colorless solid.
