To a solution of methyl (E)-3-(2-quinolinyl)-2-propenoate (2) (0.26 g 1.22 mmol) in methanol (5 ml), 5% palladium on activated carbon (0.05 g) was added and the resulting suspension was hydrogenated by vigorous stirring for 2 hours at room temperature. The reaction mixture was filtered through a short column of silica gel (ca. 2 g), the column was washed with methanol (3 ml), and the filtrate was evaporated in vacuo. The residue (0.270 g) was chromatographed on silica gel (10 g) with chloroform-ethyl acetate (9:1) as eluent to afford the title compound (0.111 g, 43%) as an oil. 1H NMR (CDCl3, HMDSO), δ: 2.93 (2H, t, J=7.2 Hz); 3.29 (2H, t, J=7.2 Hz); 3.67 (3H, s); 7.29-7.85 (4H, m); 7.89-8.11 (2H, m).
