To a solution of bromo acetic acid methyl ester (1.53 g, 0.95 ml, 10.0 mmol) and triethylamine (3.0 ml) in dry THF (25 mL) was added 4-fluoro-benzenethiol (1.62 g, 12.6 mmol) in one portion at room temperature. The resulting mixture was heated to reflux and stirred until the TLC showed the completion of the reaction. The reaction mixture was diluted with EtOAc and washed sequentially with aqueous HCl, water and saturated NaCl solution. The organic phase was then dried over anhydrous Na2SO4 and concentrated under reduced pressure to gave a crude material, which was then purified by a column chromatography with 0˜5% EtOAc in hexanes. MS: 201.3 (M+H)+.
