Procedure
19 g of redistilled thionyl chloride are added to 10.3 g of 11-[2-(2-chlorobenzoyl)-4-chlorobenzenesulphonamido]undecanoic acid in 130 ml of anhydrous benzene. After refluxing for 2 hours, the reaction medium is evaporated to dryness under vacuum and it gives a colourless oil which is used without further purification.
