Procedure

To a stirred solution of 4-hydroxy-3-methoxybenzonitrile (2.43 g, 16.29 mmol) in acetonitrile (75 mL) was added cesium carbonate (6.68 g, 20.50 mmol) and p-methoxybenzyl chloride (2.81 g, 17.92 mmol). The reaction mixture was heated to reflux and stirred. After 1 h, the mixture was allowed to cool to room temperature and was filtered. The filtrate was concentrated to provide 4.56 g (>100%) 3-methoxy-4-((4-methoxybenzyl)oxy)benzonitrile as an off-white solid. The crude material was used without purification in the next reaction.
