Procedure

5.5 g (21.2 mmol) of 3-[2-(2-quinolyl)ethenyl]benzaldehyde was dissolved in 500 ml and hydrogenated in the presence of 1.1 g of 10% palladium carbon at atmospheric pressure at room temperature for 10 hours under stirring. The 10% palladium carbon was filtered out through celite, and the filtrate was evaporated in vacuo. The residue was purified by silica gel column chromatography (eluent; n-hexane:ethyl acetate=9:1) to give 2.8 g (10.7 mmol) of the title compound in a yield of 51%.
