실험 절차

To a solution of ethyl 2-(2-(methylsulfonyl)phenoxy)acetate (750 mg, 2.9 mmol) in EtOH (15 ml) was added 10% NaOH aqueous solution (15 mL) at 26° C. The mixture was stirred for 30 min and then concentrated and the residue diluted with water (20 mL) and washed with ethyl acetate (2×20 mL). The aqueous layer was then acidified with 2N HCL until pH 3 and then extracted with ethyl acetate (2×20 ml). The combined organic layers were washed with brine (30 mL), dried over Na2SO4 and concentrated to give the title compound which was used in next step without further purification.
