실험 절차

To a solution of 4-bromo-3-(trifluoromethyl)benzyl methanesulfonate 46-4 (1.295 g, 3.75 mmol) in ethanol (10 mL) was added a solution of potassium cyanide (364 mg, 5.6 mmol) in water (2 mL). The mixture was refluxed for 2 hours. After the mixture was cooled down to the room temperature, all the solvents were evaporated and the residue was redissolved in dichloromethane (50 mL), washed with water and brine, dried over Na2SO4, and concentrated to dryness to give 2-(4-bromo-3-(trifluoromethyl)phenyl)acetonitrile 46-5 as dark brown oil, which was used for next step directly. MS m/z 264.1 (M+1)
