Versuchsvorschrift

To a mixture of 4-chloro-3-methylsulfanyl-benzenesulfonic acid (24 mmol) in anhydrous toluene (100 mL) at 0° C. was added thionyl chloride (2.62 mL, 36 mmol). The ice bath was removed and the reaction heated to 85° C. for 5 h, then 70° C. for 18 h. Unreacted starting material was still present by LC-MS and thionyl chloride (5 mL) was added and the reaction stirred for 18 hours at 70° C. The solvent was removed to give a black oil (470 mg, 8%) that was used as is in the next reaction.
