A mixture of 4-chloro-6-quinolinecarbaldehyde (3.24 g, 16.92 mmol), 4-pyridylboronic acid (3.12 g, 25.38 mmol), tetrakistriphenylphosphine palladium (0) (0.978 g, 0.846 mmol), and 2M aqueous K2CO3 (7.02 g, 50.76 mmol, 25.4 mls of 2M solution) in DMF (100 mL) was heated at 100° C. for 3.0 h and cooled to room temperature. The mixture was filtered through Celite and the Celite was washed with EtOAc. The filtrate was transferred to a separatory funnel, washed with water and saturated NaCl, dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (5% MeOH:CH2Cl2) to give the title compound (2.03 g, 51%) as a tan solid. MS (ES)+ m/e 235 [M+H]+.
