Reaktionsschritte

To a solution of potassium 4-hydroxy-2,2-dimethylbutyrate (1.92 mmol; 327 mg) in DMF (6 mL) is added ethyl iodide (2.30 mmol; 359 mg). The reaction mixture is stirred for 2 hours, and quenched with saturated ammonium chloride solution. The product is extracted three times with EtOAc. The combined organic layer is washed with aqueous 0.1 M HCl then brine, dried over Na2SO4, filtered, concentrated under reduced pressure to give 4-Hydroxy-2,2-dimethylbutyric acid ethyl ester (520 mg) contaminated with DMF.
