Reaktionsschritte
A mixture of Example 7a (0.100 g, 0.247 mmol), 2,6-difluorobenzamide (0.066 g, 0.421 mmol), cesium carbonate (0.105 g, 0.322 mmol), palladium (II) acetate (2.78 mg, 0.012 mmol), and Xantphos (10.73 mg, 0.019 mmol) in dioxane (3 mL) and DMF (0.1 mL) was heated at 150° C. for 30 minutes in a Biotage microwave reactor. The mixture was concentrated. The solid was suspended in dioxane (3 mL), treated with NaOH (20%, 0.10 mL), and heated at 50° C. for 3 hours. The reaction mixture was concentrated. The residue was stirred in water for 15 minutes, filtered, and purified by reverse-phase HPLC as described in Example 56 to give the title compound (8.5 mg) as trifluoroacetic acid salts. 1H NMR (500 MHz, DMSO-d6) ppm 7.24 (t, J=8.24 Hz, 2H), 7.30 (dd, J=8.09, 4.73 Hz, 1H), 7.52-7.65 (m, 2H), 7.70 (s, 1H), 8.34-8.41 (m, 3H), 8.65 (s, 1H), 11.66 (s, 1H), 12.41 (s, 1H). MS (ESI+) m/z 384.9 (M+H)+.
