Reaction Steps

5-methoxybenzofuran boronic acid (1.2 mmol), 6-bromonicotinamide (1.0 mmol), Pd(PPh3)2Cl2 (0.024 mmol) and NEt3 (317 μL) were mixed in EtOH (10 mL) in a 20 mL microwave vial. The mixture was stirred at 140° C. for 10 min in a microwave reactor. The mixture was filtered, the obtained precipitate was washed with water and EtOAc and dried under vacuum to afford the title compound (85 mg). 1H NMR δ ppm 9.14 (d, 1 H) 8.42 (dd, 1 H) 7.97-8.25 (m, 2 H) 7.63-7.80 (m, 2 H) 7.58 (d, 1 H) 7.22 (d, 1 H) 6.98 (dd, 1H) 3.81 (s, 3 H); MS m/z 269 (M+H).
