4-Hydroxybenzaldehyde → 4-[(2-methylbenzyl)oxy]benzaldehyde

Participants

Reaction Steps

4-Hydroxybenzaldehyde (10.0 g, 81.9 mmol) and 2-methyl benzyl bromide (40.0 g, 98.3 mmol) were dissolved in dimethylformamide (100 mL), and cesium carbonate (18.2 g, 123 mmol) was added thereto, and then, the resulting mixture was stirred under a nitrogen atmosphere at room temperature for 1 hour. Water was added to the reaction solution, and the organic matter was extracted with diethyl ether. The organic layer was washed with water and a saturated sodium chloride solution, then dried over anhydrous magnesium sulfate and filtered. Then, the solvent was distilled off under reduced pressure, whereby a crude product was obtained. This crude product was purified by silica gel column chromatography (hexane:ethyl acetate=100:0 to 60:40 (v/v)), whereby the objective title compound was obtained as a colorless oily substance (19.2 g, yield: 103%).
