Procedure

10 g (36.5 mmol) of 2-(bromomethyl)-3-nitrobenzoic acid methyl ester is mixed with 36 ml of N,N-dimethylformamide and 24 ml of water. After 3.54 g of sodium azide is added, the batch is stirred overnight. The reaction mixture is diluted with methyl-tert butyl ether, and washed twice with water and once with brine. After drying on sodium sulfate, it is filtered, and the solvent is spun off. The desired azide is obtained in a yield of 89.6% (7.72 g) and further incorporated in crude form.
