반응 단계

To a solution of ethyl 2-(p-tolyloxy)acetate (200 mg, 1 mmol) in EtOH (10 ml) was added 10% NaOH solution (10 ml) at 26° C. The mixture was stirred for 30 min, concentrated then water (20 mL) added to it before washing with ethyl acetate (2×20 mL). The aqueous layer was acidified with 2N HCL until pH 3 and extracted with EA (2×20 ml). The organic layer was washed with brine (30 mL), dried over Na2SO4 and concentrated to give the title compound which was used in next step without further purification.
