Reaktionsschritte
A mixture of 2,2-dimethylbutyrolactone (6.84 g, 60 mmol) and KOH (3.36 g) in H2O (60 mL) was heated at reflux for 2 h. The solution was cooled to room temperature and acidified to pH 5 with aqueous HCl solution. The mixture was then extracted with ethyl acetate 3 times. The combined organic layers were washed with brine, dried over Na2SO4, concentrated under reduced pressure to give 4-hydroxy-2,2-dimethyl-butanoic acid compound 54-B (4 g).
