To a solution of 3-[2-(2,4dichloro-benzoyl)-3methyl-benzofuran-6-yl]-benzoic acid (40 mg, 0.09 mmol) in dichloromethane (2 mL) was added 2-methoxyethylamine (0.02 mL, 0.19 mmol), EDCI (20 mg, 0.1 mmol), DMAP (1 mg, 0.01 mmol), and N,N-diisopropylethylamine (0.02 mL, 0.1 mmol). The reaction mixture was stirred at rt overnight, then concentrated in vacuo and purified by prep-HPLC to afford the desired product (11 mg, 25%). 1H-NMR (CDCl3) δ 8.05 (t, J=1.8 Hz, 1H), 7.77-7.75 (m, 3H), 7.69 (m, 1H), 7.60 (dd, J=8.3, 1.0 Hz, 1H), 7.51 (m, 2H), 7.47 (m, 1H), 7.40 (ddd, J=8.2, 1.9, 0.5 Hz, 1H), 6.62 (t, J=4.5 Hz, 1H), 3.70 (m, 2H), 3.60 (m, 2H), 3.40 (s, 3H), 2.62 (s, 3H).
