Versuchsvorschrift

In a three-necked flask fitted with stirrer and dropping funnel 65 g of sodium azide is dissolved in 900 ccs of water. While stirring and cooling till 0°-5° C a solution of 198 g of m-chlorosulphonyl-benzoic acid in 900 ccs of acetone is added dropwise. Then stirring is continued for 30 minutes whereupon the solution obtained is poured into 2 liters of water. The white precipitate formed is sucked off, washed with water and dried in vacuo. Melting point: 143° C.
