Versuchsvorschrift
A solution of 5-chloro-2-hydroxy-benzoic acid (20.0 g, 116 mmol) in heptane (232 mL, 0.5 M) was treated with thionyl chloride (25.4 mL, 348 mmol) and heated to 60° C. for 6 h. After cooling to room temperature, the solution was concentrated under reduced pressure to give 5-chloro-2-hydroxy-benzoyl chloride as a thick yellow oil (22 g) which was used without further purification.
