Versuchsvorschrift

A solution of 3 g of ethyl 2-hydroxy-6-vinylbenzoate (see Example 1a), 150 ml of methanol and 45 ml of 10% by weight sodium hydroxide solution was boiled for 8 h. It was then poured into ice-water at pH 1 (hydrochloric acid) and extracted with ethyl acetate, and the solution was dried over sodium sulfate and evaporated under reduced pressure.
