Reaction Steps
A mixture of 3-methyl-4-[3-(piperidin-4-ylamino)-propoxy]-benzofuran-2-carboxylic acid ethyl ester (15 mg), 3-(chloromethyl)pyridine hydrochloride (8 mg) and N,N-diisopropylethylamine (22 μl) in ethanol (1.5 ml) was stirred overnight at 70° C. The reaction mixture was dissolved in ethyl acetate and washed with saturated ammonium chloride solution and water. The organic solvent was dried over anhydrous sodium sulfate and evaporated to dryness. The residue was purified by silica gel column chromatography (dichloromethane-MeOH) to afford 3-methyl-4-[3-(1-pyridin-3-ylmethyl-piperidin-4-ylamino)-propoxy]-benzofuran-2-carboxylic acid ethyl ester (8 mg) as a colorless oil. FAB-MS: m/z 452 (MH+); 1H-NMR (CDCl3): δ 1.43 (3H, t, J=7 Hz), 1.60 (2H, m), 2.00 (4H, m), 2.20 (2H, quintet, J=6.5 Hz), 2.70 (1H, m), 2.72 (3H, s), 2.86 (2H, br d, J=12 Hz), 2.99 (2H, t, J=7 Hz), 3.49 (2H, s), 4.15 (2H, t, J=6 Hz), 4.43 (2H, q, J=7 Hz), 6.59 (1H, d, J=8 Hz), 7.11 (1H, d, J328 Hz), 7.22 (1H, m), 7.29 (1H, t, J=8 Hz), 7.66 (1H, brd, J=8 Hz), 8.48 (1H, m), 8.51 (1H, br s).
