Potassium Carbonate → HCID 86639493, compound

Participants

Reaction Steps

To a suspension of 4-diethylamino-2-hydroxybenzaldehyde (300 mg, 1.55 mmol), potassium carbonate (428 mg, 3.10 mmol), and tetrabutylammonium iodide (57 mg, 0.15 mmol) in 1.6 mL of dry N,N-dimethylformamide was added 4-methoxybenzyl chloride (0.31 mL, 2.3 mmol) at 0° C. After being stirred at room temperature for 2 h, the reaction mixture was filtered to remove inorganic salts. The filtrate was diluted with diethyl ether, and the solution was washed with water, saturated NaHCO3 aqueous solution, brine, and dried over MgSO4. After filtration, the filtrate was concentrated in vacuo, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=90/10 to 80/20) to obtain the title compound as a colorless oil (493 mg, quant.).
