Reaction Steps

Potassium tert-pentoxide 1.7 M in toluene (7.35 mL, 12.5 mmol) was added drop wise to a solution of methyl 2-chloro-5-(trifluoromethyl)benzoate (2.0 g, 8.38 mmol) and ACN (1.32 mL, 25.15 mmol) in anhydrous toluene (30 mL). The mixture was stirred at room temperature for 20 min, then diluted with HCl 1 N (20 mL), water (75 mL) and EtOAc (100 mL). The organic layer was separated, washed with water (50 mL×2) and brine (50 mL×2), dried over sodium sulfate and concentrated. Column chromatography on silica gel (0 to 20% EtOAc/hexane) provided the title compound (1.73 g, 83%).
