Reaktionsschritte

12 g (27.5 mmol) of methyl 2-hydroxy-3-(2-(3,4-dimethoxyphenyl)ethoxy)-3,3-diphenylpropionate were dissolved in 110 ml of dioxane, and 55 ml of 1 N NaOH solution were added. The mixture was stirred at 80° C. for 2 hours. Water was added to the mixture, and the aqueous phase was extracted twice with ether. The aqueous phase was acidified with 1 N aqueous HCl and extracted with ether, the organic phase was dried over magnesium sulfate, and the solvent was distilled off. The residue was recrystallized from ether/n-hexane, and 10.2 g (87%) of colorless crystals were isolated.
