Reaktionsschritte
Step B To the mixture of 4-hydroxy-2,2-dimethyl-butanoic acid monopotassium salt (60 mmol) and benzyl bromide (8.55 mL, 72 mmol) were added NaI (10.8 g, 72 mmol) and K2CO3 (8.29 g, 60 mmol). The reaction mixture was stirred at reflux for 18 h. The precipitate was filtered off and the filtrate was evaporated. The residue was purified by flash column chromatography (EtOAc: hexanes=1:2) to give 4-hydroxy-2,2-dimethyl-butyric acid benzyl ester as a colorless oil (9 g, 67%)
