Reaktionsschritte

To a solution of 4-tert-butyl toluene (33.7 mmol) in acetonitrile (150 mL) at 0° C. was added nitronium tetrafluoroborate (40.5 mmol). After 30 min at room temperature, the reaction was diluted with water (50 mL) and extracted with EtOAc (3×30 mL). The combined organic extracts were washed with brine and dried (MgSO4). Removal of the volatiles in vacuo left a residue; flash chromatography using 10% methylene chloride/petroleum ether as eluent provided 4-tert-butyl-2-nitrotoluene.
