Versuchsvorschrift
10 g of 3-hydroxyphenylacetic acid are dissolved in 60 ml of methanol and 2.5 ml of sulphuric acid. The solution is heated at reflux for two hours. It is brought back to ambient temperature and the methanol is evaporated. The residue is taken up in a saturated K2CO3 solution. Extraction is carried out with AcOEt. The organic phase is dried over MgSO4, filtered and evaporated to dryness. 11.1 g of oil are obtained.
