Mix 4-ethoxybenzyl alcohol (3.35 g. 22 mmol), 3-hydroxy-benzaldehyde (2.69 g, 22 mmol), triphenylphosphine (5.8 g, 22 mmol) and diethylazadicarboxylate (3.83 g, 22 mmol) in tetrahydrofuran (25 mL). Stirat room temperature under anhydrous atmosphere until the reaction is done. Concentrate the solution in vacuo and dilute with a small quantity of ethyl ether. Filter any precipitate and concentrate the filtrat in vacuo. Purify by silica gel chromatography to give 3-(4-ethoxybenzyloxy)benzaldehyde.
