Versuchsvorschrift
399 g (2.56 mol) of p-toluonitrile were added over the course of 90 minutes to 1 l of fuming nitric acid at -10° C. 1 h after the addition, the mixture was poured onto 2.5 l of ice/H2O, whereupon a solid precipitated and was removed on a suction filter funnel and washed to neutral pH with water. The yield of the product was 363 g (88%). 1H-NMR (CDCl3 ; δ in ppm): 8.3 (d, 1H); 7.8 (dd, 1H); 7.5 (dd, 1H); 2.7 (s, 3H)
