Versuchsvorschrift

80 ml of thionyl chloride was gradually added to a benzene suspension of 217 g of 5-bromosalicyclic acid and 113 g of phenol, followed by refluxing for ten hours under heating. After distilling off the benzene, ice-water was added to the residue, and the precipitate formed was collected by filtration, followed by drying. Yield: 210 g.
