Reaction Conditions

Reaction Steps

5-methoxybenzofuran boronic acid (1.2 mmol), 5-bromopyridine-2-carboxamide (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, filtered, and the precipitate was washed with water and EtOAc and dried under vacuum to afford the title compound (75 mg). 1H NMR δ ppm 9.10 (d, 1 H) 8.34 (dd, 1 H) 8.21 (br. s., 1 H) 8.00 (d, 1 H) 7.52-7.72 (m, 3 H) 7.25 (d, 1 H) 7.00 (dd, 1 H) 3.82 (s, 3H); MS m/z 269 (M+H).
