Procedure

To a suspension of 12 g of 2-chloro-5-chlorosulphonylbenzoic acid in 150 ccs of ethanol, a solution of 10 g of sodium azide in 30 ccs of water and 120 ccs of ethanol is dropwise added whilst stirring. Stirring is continued overnight and the inorganic constituents are precipitated with acetone. After allowing to stand at 0° C for a relatively long period, the precipitate is filtered off and the mother liquor is carefully evaporated to dryness by means of a rotary evaporator.
