Versuchsvorschrift

With stirring, concentrated H2SO4 (205 ml) was cooled to 5° C. Keeping the temperature below 20° C., concentrated HNO3 (85 ml) was added dropwise. Keeping the temperature below 40° C., p-tolunitrile (96 ml) was then added dropwise. After stirring 10 minutes, the reaction mixture was quenched onto 3 kilograms ice, granulated and filtered to yield title product: 120.5 g; m.p. 102°-104°.
