反応手順

To a stirred solution of NaH (64 mg, 0.13 mmol) in DMF (15 mL) was added ethyl 2-(5-chloro-6-(cyclopropylmethoxy)-4′-(trifluoromethyl)biphenyl-3-yl)acetate (500 mg, 0.12 mmol) and 1,1,1-trifluoro-2-iodoethane (0.304 mL, 0.15 mmol) at 0° C. The reaction mixture was stirred at 0° C. over a period of 30 min. After completion of starting material (by TLC), diluted with water (20 mL), acidified with 1N HCl (pH=5) and extracted with EtOAc (3×30 mL). Combined organic layers were washed with water (3×15 mL), brine and dried over anhydrous Na2SO4. After filtration and evaporation, the crude material was purified by column chromatography to afford ethyl 2-(5-chloro-6-(cyclopropylmethoxy)-4′-(trifluoromethyl)biphenyl-3-yl)-4,4,4-trifluorobutanoate (300 mg) as liquid.
