Procedure

2-[5-(3-Bromo-propoxy)-indol-1-yl]-propionic acid methyl ester (Example 48, 170.20 mg, 0.50 mmol) and 4-(4-ethyl-oxazol-2-yl)-2-methoxy-phenol (Example 39, 109.68 mg, 0.50 mmol) were dissolved in DMF (2 mL) at rt. Cesium carbonate (244.5 mg, 0.75 mmol) was added to the solution, followed by three drops of water. The mixture was stirred at rt for 17 h. The crude reaction mixture was filtered and purified by HPLC. The desired product was isolated as a white solid (143.8 mg, 60.1%). LC/MS m/z 479.3 (M+H)+; RT 3.59 min. 1H NMR (400 MHz, CD2Cl2) δ 7.58 (d, 1H), 7.56 (s, 1H), 7.41 (m, 1H), 7.24 (d, 1H), 7.19 (d, 1H), 7.11 (d, 1H), 7.00 (d, 1H), 6.88 (dd, 1H), 6.46 (d, 1H), 5.11 (q, 1H), 4.28 (t, 2H), 4.22 (t, 2H), 3.93 (s, 3H), 3.71 (s, 3H), 2.61 (q, 2H), 2.34 (m, 2H), 1.82 (d, 3H), 1.29 (t, 3H).
