Versuchsvorschrift

In the first step, salicylic acid is mixed with thionyl (or oxalyl) halide, most preferably chloride, (molar ratio in the general range of from 1:1 to 2:1) in an anhydrous, typically non-polar, solvent, in the presence of pyridine catalyst, at a temperature of from 20 to 45° C. for 0.5-2 hours. At the end of this reaction, salicylic acid chloride id obtained. Optionally, the solvent is distilled at least partially.
