Procedure

3-Hydroxybenzonitrile (1.19 g, 10 mmol) and 4-bromo-2-methyl-2-butene (1.66 g, 10 mmol) were dissolved in N,N-dimethylformamide (5 mL), potassium carbonate (1.66 g, 12 mmol) was added, and the solution was stirred at room temperature for 2 hours. Water (50 mL) was added to the reaction solution, which was then extracted with ethyl acetate (50 mL). The extract was washed, then, dried over anhydrous magnesium sulfate, and the solvent was evaporated in vacuo. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=95:5), and the title compound (1.71 g, 10 mmol, 99.4%) was obtained as a colorless oil.
