반응 단계

A suspension of 4-hydroxybenzaldehyde (200 mg, 1.64 mmol), 1-chloro-3,3-dimethylbutane (395 mg, 1.97 mmol), sodium iodide (24 mg, 0.16 mmol), and cesium carbonate (800 mg, 2.46 mmol) in anhydrous dimethylformamide (5 mL) was stirred at 80° C. overnight. After cooling to room temperature, solids were filtered and washed with ether. The filtrate was washed with 2 N sodium hydroxide (2×20 mL), water (20 mL), and brine (20 mL), dried over magnesium sulfate, filtered, and concentrated to give 4-(3,3-dimethylbutoxyl)benzaldehyde (262 mg, 78% crude) as a pale yellow oil that was used without further purification or characterization.
