Reaction Steps
Potassium cyanide (630 mg) was added to an emulsion of 4-bromo-1-bromomethyl-2-trifluoromethylbenzene (3.86 g) in ethanol (15 mL)-water (5 mL), and the mixture was stirred at 70° C. for three hours and 15 minutes. Water and ethyl acetate were added to the reaction solution, and the organic layer was separated. The resulting organic layer was washed with brine, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (carrier: Wakogel C-200; elution solvent:heptane:ethyl acetate=9:1) to obtain 2.28 g of the title compound. The property values of the compound are as follows.
