Reaktionsschritte

5-methoxybenzofuran boronic acid 1.2 mmol), 6-bromo-3-pyridazinamine (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 solvent was removed under vacuum, water was added and the solution was extracted with EtOAc. The organic layer was dried over Na2SO4, filtered and the solvent removed under vacuum. The crude substance was purified by preparative HPLC to afford the title compound as a white solid (51 mg). 1H NMR δ ppm 7.77 (d, 1 H) 7.52 (d, 1 H) 7.35 (s, 1H) 7.19 (d, 1 H) 6.79-6.98 (m, 2 H) 6.72 (s, 2 H) 3.80 (s, 3 H); MS m/z 242 (M+H).
