Procedure

To 3-bromo-5-(trifluoromethyl)benzaldehyde (1.0 g, 3.95 mmol) in 1,4-dioxane (15 ml), pyridine-4-boronic acid) (583 mg, 4.74 mmol), sodium carbonate (2M aqueous solution) (1.67 gms in 7.9 ml water) and Pd(PPh3)4 450 mg, 0.39 mmol) was added and heated at 90° C. for 5 h. Then reaction mixture was diluted with ether, washed with water, brine and dried. Volatiles were removed under vacuum and the crude residue was column chromatographed (50% ethylacetate/50% hexanes) to yield 250 mg of 3-(pyridin-4-yl)-5-(trifluoromethyl)benzaldehyde.
