Reaction Steps
To a solution of 4-tert-butyl toluene (5 g, 33.7 mmol) in acetonitrile (150 mL) at 0° C. was added nitronium tetrafluoroborate (5.83 g, 40.5 mmol). After 30 min at room temperature, the reaction was diluted with water (50 mL) and extracted with ethyl acetate (3×30 mL). The combined organic extracts were washed with brine and dried (MgSO4). Removal of the volatiles in vacuo left a residue which was purified by flash chromatography using 10% methylene chloride in petroleum ether as eluent. Concentration in vacuo of the product rich fractions provided 3.8 g of 4-tert-butyl-2-nitrotoluene.
