Versuchsvorschrift
A suspension of 1.1 g (5.02 mMol) of the sodium salt of 4-cyanobenzenemethanesulphonic acid in 20 ml of acetonitrile was mixed with 1.2 g (5.76 mMol) of phosphorus-(V)-chloride and then refluxed for 24 hours. The insoluble matter was filtered off and the filtrate was evaporated down in vacuo. Yield; 0.8 g (74% of theory). The product was used in the next step without purification.
