Prepared according to Procedure A using 2,8-dichloroquinoline 3-carbaldehyde (1.70 g, 7.5 mmol), 2-chlorophenyl boronic acid (1.29 g, 8.25 mmol, 1.1 eq), tetrakis(triphenylphosphine)palladium (0.430 g, 0.375 mmol, 0.05 eq), and sodium carbonate (3.97 g, 37.5 mmol, 5 eq) in acetonitrile (57 mL) and water (19 mL). After purification, 8-chloro-2-(2-chlorophenyl)quinoline-3-carbaldehyde was obtained as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 10.25 (1 H, s), 8.93 (1 H, s), 8.14 (1 H, d, J=8.6 Hz), 8.03 (1 H, d, J=9.0 Hz), 7.55-7.64 (1 H, t, J=8.0 Hz) Mass Spectrum (ESI) m/e=302.0 and 304.0 (M+1)
