Reaktionsschritte

To a solution of ethyl 2-methyl-2-phenoxypropanoate (210 mg, 1 mmol) in EtOH (10 ml) was added 10% NaOH aqueous solution (10 mL) at 26° C. The mixture was stirred for 30 min and then concentrated before the addition of water (20 mL) and washing with ethyl acetate (2×20 mL). The aqueous layer was acidified with 2N HCL until pH 3 and extracted with ethyl acetate (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.
