Procedure

Potassium carbonate (5.04 g, 36.5 mmol) was added at room temperature to a solution of 4-amino-o-cresol (3.00 g, 24.4 mmol) and ethyl bromoacetate (2.70 mL, 24.4 mmol) in DMF (30 mL). The resulting solution was stirred at room temperature for 1.5 hours. Water was added to the reaction mixture, and extracted with ethyl acetate. The ethyl acetate layer was washed with brine. The ethyl acetate layer was dried over anhydrous sodium sulfate, and evaporated. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=3:1), to thereby yield 5.10 g of the title compound.
