Procedure
2-Chloro-4-hydroxybenzaldehyde (324 mg, 2.07 mmol), 3,4-dichlorobenzyl alcohol (513 mg, 2.90 mmol), and triphenylphosphine (760 mg, 2.90 mmol) were dissolved in tetrahydrofuran (8 mL), and a diethyl azodicarboxylate toluene solution (2.2 M, 1.32 mL, 2.90 mmol) was slowly added dropwise thereto at room temperature, and then, the resulting mixture was stirred under a nitrogen atmosphere at room temperature for 2 hours. The solvent in the reaction solution was distilled off under reduced pressure, and the resulting residue was washed with hexane/dichloromethane (6/1 (v/v)), whereby the objective title compound was obtained as a white solid (244 mg, yield: 37%).
