Vorschrift

A solution of 4-phenoxybenzenesulfonic acid (3.14 g, 12.64 mmol) in thionyl chloride (9 ml) was refluxed for 4 h in presence of DMF (2 drops). After cooling to room temperature, diethyl ether (20 ml) was added and the resulting white solid was separated by filtration. The filtered solution was evaporated in vacuo to give 4-phenoxybenzenesulfonyl chloride as a brown oil which was used in the next step without further purification.
