実験手順
To a solution of 4-bromo-3,5-dimethylphenol (500 mg) and Cs2CO3 (1.3 g) in N,N-dimethylformamide (5 mL) is added 2-bromoacetonitrile (290 μL) and the mixture is stirred for 2 hours at 35° C. The mixture is poured on water and stirred for 15 minutes. The precipitate is folitered off and dried to give the title compound. Yield: 535 mg; Mass spectrum (EI): m/z=239 [M]+.
