Versuchsvorschrift

To a solution of pentamethylbenzene (5 g, 33.8 mmol) in dichloromethane (250 mL) at 0° C. was quickly added nitronium tetrafluoroborate (5 g). The mixture was stirred for 4 h before it was quenched with cold water. The organic layer was concentrated and the residue was reduced (Example 14, procedure C) to give pentamethylaniline in 52% yield.
