Versuchsvorschrift
77 g of (4S)-2,2-dimethyl-4-(4-cyanophenoxy)methyl-1,3-dioxolane, was dissolved in methanol (200 ml) and water (75 ml). Concentrated hydrochloric acid (0.5 ml) was added and the mixture was kept at 50° C. overnight. It was evaporated at reduced pressure and recrystallized from water to yield 46 g of the title compound as white leaves, m.p. 63°-65° C.
