Versuchsvorschrift

Concentrated hydrochloric acid (5 mL) was added to a solution of 2-(4-(2,2-diethoxyethoxy)phenyl)ethanol (example 3, step a) (0.76 g) in 1,4-dioxane (10 mL) and the resulting mixture was stirred for 1 h. The reaction was diluted with water (50 mL) and extracted with ethyl acetate (3×50 mL). The combined organic solutions were washed with water (50 mL) and brine (50 mL), then dried over sodium sulphate, filtered and evaporated in vacuo to give the subtitled compound, which was used directly. Yield 0.35 g.
