After allowing to cool to room temperature, the reaction mixture was extracted with toluene. After drying over magnesium sulfate, it was distilled under reduced pressure. The obtained oily solid was purified by silica gel chromatography to obtain 2-phenyl-3- (4-chlorophenyl) pyridine, which is the target product of the white solid (yield 7.00 g, yield 98%).

A 4 M potassium phosphate (140 mL) was added to this suspension, and the mixture was heated under reflux for 10 h. After cooling to room temperature, toluene was added to the reaction mixture, and the organic layer was extracted. Magnesium sulfate and activated charcoal were added to the organic layer, and insoluble components were filtered off. The filtrate was concentrated, and then purified by recrystallization from ethanol to obtain the desired 3-chloro-5-(2-phenylpyridin-3-yl)biphenyl (5-1) (45.5 g, 71%). 1H-NMR (CDCl3): δ 8.73 (dd, 4.8, 1.7 Hz, 1H), 7.79 (dd, t. t, 1.7 Hz, 1H), 7.46 (t, 1.8 Hz, 1H), 7.42-7.30 (m, 9H), 7.27 (d, 1.8 Hz, 1H), 7.25-7.24 (m, 2H), 7.18 (t, 1.6 Hz, 1H).
