Versuchsvorschrift

To a solution of 4-acetyl-benzamide (Ex-92A, 0.25 g, 1.53 mmol) and 2-(2-morpholin-4-yl-ethoxy)-4-methoxy-5-thiophen-2-yl-benzaldehyde (Ex-60A, 0.53 g, 1.53 mmol) in DMF (7 mL) and methanol (3 mL) was added lithium methoxide. The solution was allowed to stir at ambient temperature. The reaction was quenched with water after 2 hours. The aqueous solution was extracted with ethyl acetate. The combined extract was washed with NaHCO3, NH4Cl, brine, dried (Na2SO4) and concentrated. The residue was stirred in ethanol overnight to afford the title compound as a yellow solid (0.43 g, 57%), mp 183–184° C. 1H-NMR (CDCl3) δ 8.09–8.04 (m, 3H), 7.93 (d, J=8.3 Hz, 2H), 7.87 (s, 1H), 7.57 (d, J=15.7 Hz, 1H), 7.42 (d, J=3.9 Hz, 1H), 7.32 (d, 4.4 Hz, 1H), 7.11–7.08 (m, 1H), 6.55 (s, 1H), 6.25 (bs, 1H), 5.75 (bs, 1H), 4.25 (t, J=5.9 Hz, 2H), 3.98 (s, 3H), 3.71 (t, J=4.2 Hz, 4H), 2.92 (t, J=5.7 Hz, 2H), 2.59 (t, J=4.6 Hz, 4H). MS m/z=493 ([M+H]+, 100%).
