Procedure

To a solution of 4-[3E-(5-Benzo[b]thien-2-yl-2,4-dimethoxyphenyl)-acryloyl]-benzoic acid (Ex-3, 0.44 mg, 1 mmol) and 2-morpholin-4-yl-ethylamine (0.18 mL) in dichloromethane (20 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.38 g, 2 mmol) and the mixture was stirred at room temperature for four hours. It was poured into brine (100 mL) and extracted with dichloromethane (2×50 mL). The organic phase was dried and evaporated. Chromatography (dichloromethane/methanol 50:1) gave the title compound as a yellow solid (0.43 g, 77%). 1H-NMR (300 MHz, CDCl3) δ 8.12 (d, J=16 Hz, 1H), 8.09 (d, J=8 Hz, 2H), 7.95 (s, 1H), 7.90 (d, J=8 Hz, 2H), 7.77–7.85 (m, 2H), 7.68 (s, 1H), 7.56 (d, J=16 Hz, 1H), 7.29–7.40 (m, 2H), 6.80–6.85 (br s, 1H), 6.58 (s, 1H), 4.04 (s, 3H), 4.01 (s, 3H), 3.75 (t, J=5 Hz, 4H), 3.59 (quad, J=5 Hz, 2H), 2.64 (t, J=5 Hz, 2H), 2.53 (t, J=5 Hz, 4H).
