Reaktionsschritte

To a solution of 4-bromo-N-quinolin-7-ylbenzamide (Example 82) (50 mg, 0.153 mmol) in toluene (2 ml) and ethanol (0.4 ml) under an argon atmosphere was added 3-methyl-phenylboronic acid (21 mg, 0.153 mmol), 2M sodium carbonate solution (0.15 ml) and tetrakis(triphenylphosphine)palladium (0) (5 mg, 0.05 mmol). The reaction was heated at reflux for 18 h, then cooled to room temperature and diluted with EtOAc. The mixture was washed with sat. aq. sodium bicarbonate solution and water, dried over MgSO4 and concentrated to give the crude product which was purified by SPE column chromatography. Elution with 50% EtOAc in 40-60° C. petroleum ether gave the title compound as an off-white solid. 1H NMR (400 MHz, CDCl3) δ (ppm): 8.92 (dd, 1H), 8.19 (d, 1H), 8.13 (m, 3H), 8.01, (d, 2H), 7.86 (d, 1H), 7.75 (d, 2H), 7.46 (m, 2H), 7.36 (m, 2H), 7.25 (m, 1H), 2.46 (s, 3H).
