A solution of 3-methyl-4-nitrobenzyl chloride (0.27 g), 3,5-bis-(trifluoromethyl)phenylboronic acid (0.45 g), tetrakis(triphenylphosfine)palladium (0.1 g) and sodium carbonate (0.48 g) in water (2 ml) and 1,2-dimethoxyethane (10 ml) was stirred under an argon atmosphere at 85° C. for 2 hours. After cooling, the reaction solution was diluted with ethyl acetate and further stirred for 10 minutes by adding water thereto. After washing the organic layer with a saturated salt solution, it was dried over anhydrous magnesium sulfate. The solution was distilled off under reduced pressure and the resultant residue was purified by silica gel column chromatography to obtain 4-(3,5-bis-trifluoromethyl-benzyl)-2-methyl-nitrobenzene (0.44 g).
