Versuchsvorschrift
To stirred 3,4-dichloro-toluene 4 (10.0 g, 62.2 mmol) at 0° C. was slowly added fuming nitric acid (20.0 mL). The mixture was stirred for 2 hrs at RT, then water added (200 mL) and the reaction mixture filtered. The filtrate was purified by silica gel chromatography using 5% ethyl acetate in hexanes to give the title compound 11.7 g (92%). 1H NMR (400 MHz, CDCl3) δ8.14 (s, 1 H, Ar), 7.47 (s , 1 H, Ar), 2.59 (s, 3 H, CH3).
