Procedure
A mixture of 14.8 g of 4-nitrobenzonitril, 32 g of ammoniumchloride and 39 g of sodium azide in 150 ml of DMF was heated for 2 h at 120° C. After evaporating the solvent, the residue was partitioned between 2N hydrochloric acid and ethyl acetate. The organic layer was dried and evaporated. The residue was washed with ether and dried. M.p. 101-102° C.
