実験手順

Prepared according to the procedure described for Intermediate 41, utilising 2-chloro-7-fluoro-8-methylquinoline-3-carbaldehyde (5.0 g, 22.36 mmol), 5-methylpyridin-3-ylboronic acid (6.95 g, 50.75 mmol), tetrakis(triphenylphosphine)palladium(0) (258 mg, 0.22 mmol) and Na2CO3 (3.55 g, 33.54 mmol) in water (30 mL) and DME (60 mL). The crude material was triturated in diethyl ether (75 mL), and the solid was filtered off and dried under vacuum to give the title compound (5.0 g, 80%) as a brown solid. δH (DMSO-d6) 10.12 (s, 1H), 9.06 (s, 1H), 8.72 (d, J 1.9 Hz, 1H), 8.60 (d, J 1.5 Hz, 1H), 8.24 (dd, J 9.0, 6.4 Hz, 1H), 7.99 (d, J 0.6 Hz, 1H), 7.68 (t, J 9.2 Hz, 1H), 2.66 (d, J 2.4 Hz, 3H), 2.44 (s, 3H). LCMS (ES+) 281 (M+H)+, RT 1.66 minutes.
