Reaction Steps

3M PhMgBr in diethyl ether (1.7 mL, 5.07 mmol, 1.1 eq.) is added dropwise to the solution of 4-Bromo-2-iodo-3-methyl-benzoic acid ethyl ester (1.7 g, 4.61 mmol), LiCl (195 mg, 4.61 mmol) in dry THF (50 mL) at −10° C. The mixture is stirred at −10° C. for 2 hours. Benzaldehyde (0.977 g, 9.22 mmol) is slowly added to mixture at −10° C. This solution is stirred at room temperature for 16 hours and diluted with saturated aqueous ammonium chloride solution (100 mL). This solution is extracted with ethyl acetate (3×70 mL). The combined organic layers are washed with water and brine, dried over anhydrous sodium sulfate, concentrated in vacuo. The residue is purified by a silica chromatography to give the desire compound as a white solid.
