1.121 g of 4-pyridylboronic acid, 2.35 g of methyl 3-bromobenzoate, 7.5 g of cesium carbonate and 530 mg of tetrakistriphenyl phosphine palladium were dissolved in 40 ml of N,N-dimethylformamide, and the mixture was stirred at 120° C. overnight in a nitrogen atmosphere. The reaction mixture was diluted with ethyl acetate, washed with water and dried over anhydrous magnesium sulfate, and the solvent was removed. The residue was purified by silica gel column, to give 1.325 g of the title compound in the 4:3 hexane-ethyl acetate fraction.
