الإجراء التجريبي

A solution Of 4.2 g (15.7 mmol) 4-cyano-1-ethoxalylaminonaphthalene in 125 ml glacial acetic acid was added 125 ml acetic anhydride. At 15° C. a solution of 12 ml 100% nitric acid in 60 ml glacial acetic acid Was added dropwise. Stirring was continued at 25° C. for 24 h and then at 50° C. for 1.5 h. The reaction mixture was poured into 500 ml ice-water to give 3.5 g (72%). M.p. 178.0° C.
