Reaction Conditions

Reaction Steps

To a solution of 60% sodium hydride (436 mg, 18.2 mmol) in DMF (2.0 mL) was added hydroquinone (1.0 g, 18.2 mmol) in DMF (10.0 mL) dropwisely. The solution was added with 2-methoxyethyl 4-methylbenzenesulfonate (12-2, 2.10 g, 21.8 mmol) dropwisely. The reaction was stirred at 65° C. for 16 h. The solution was cooled to room temperature, poured into icy H2O, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous MgSO4(s), and concentrated under reduced pressure to give 4-(2-methoxyethoxy)phenol (12-3, 1.0 g), which was used directly for the next step without further purification.
