Versuchsvorschrift
A mixture of 2,3-bis(2-hydroxyethyl)-phenol (1.2 g) and 36% aqueous hydrochloric acid (24 ml) was heated at reflux for 2 h. The mixture was cooled, diluted with water (24 ml) and extracted with ethyl acetate (2×24 ml). The combined extracts were dried (Na2SO4) and the solvent evaporated to give the title compound (1.2 g) as a brown oil.
