Reaction Steps

To a mixture of 1.0 g (4.0 mmol) 4-ethoxalylaminobenzonitril in 4 ml glacial acetic acid was added 4 ml acetic anhydride. At 0° C. a solution of 1 ml 100% nitric acid in 2 ml glacial acetic acid was added dropwise, and after 15 min. further 1 ml 100% nitric acid was added. Stirring was continued at 0° C. for 1 h. The reaction mixture was poured into 50 ml ice-water to give 0.95 g (81%) of 4-ethoxalylamino-3-nitrobenzonitril. M.p. 151.8° C.
