Reaction Steps

Palladium acetate (0.005 g, 0.022 mmol) and 2-(dicyclohexylphosphino)biphenyl (0.015 g, 0.044 mmol) were added to a solution of (4-formylphenyl)boronic acid (0.25 g, 1.65 mmol), 1-bromo-3-chloro-4-octoxybenzene (0.35 g, 1.10 mmol, from Step A), and potassium fluoride (0.19 g, 3.30 mmol) in 1,4-dioxane (3 mL). The reaction mixture was heated at 75° C. for 3 h. The reaction was cooled, filtered through celite and concentrated in vacuo. Silica gel chromatography eluting with 1% ethyl acetate/hexane yielded 0.17 g of desired product: 1H NMR (500 MHz, CD3OD): δ 10.01 (s, 1H), 7.97 (d, J=8.0 Hz, 2H), 7.80 (d, J=8.0 Hz, 2H), 7.74 (s, 1H), 7.61 (d, J=7.7 Hz, 1H), 7.16 (d, J=8.7 Hz, 1H) 4.11 (t, J=6.2 Hz, 2H), 1.80-1.89 (m, 2H), 1.50-1.60 (m, 2H), 1.28-1.46 (m, 8H), 0.88-0.97 (m, 3H)
