Reaktionsschritte
A mixture of 4-hydroxy-2,2-dimethylbutyric acid monopotassium salt (10.6 g,62.35 mmol) and phenylmethyl bromide (11.63 g, 68 mmol) in 100 ml of DMF was stirred at room temperature for 24 hours and then the mixture was poured into ice/water. The mixture was extracted with ether (3×) and the organic layer was washed with brine, dried over sodium sulfate, and concentrated in vacuo. The residue was purified by column chromatography (silica, 12-66% of ethyl acetate/hexane) to afford 10.02 g (72%) of 4-hydroxy-2,2-dimethylbutyric acid phenylmethyl ester.
