To a solution of 4-isopropylphenol (1.007 g, 7.39 mmol) in 15 mL dimethylformamide was added potassium carbonate (2.04 g, 14.79 mmol) and ethyl bromoacetate (1.23 mL, 11.09 mmol). The reaction was stirred for 48 h at ambient temperature. The mixture was diluted with 500 mL water and extracted with diethyl ether (2×200 mL). The organic extracts were combined, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resultant oil was flash chromatographed with 10% ethyl acetate/hexanes to yield 1.61 g (98%) of ethyl-(4-isopropylphenoxy)acetate as a clear oil.
