Reaction Steps
To a solution of 1-bromo-4-ethylbenzene (7 g, 37.8 mmol) in 9 mL concentrated H2SO4 at −20° C. was added a mixture of H2SO4 (3.74 g, 41.9 mmol) and HNO3 (2.64 g, 41.9 mmol). The mixture was stirred at −20° C. for 2 h. Water was added and the mixture was extracted with EtOAc. The organic phase was washed with aqueous NaHCO3 and brine, dried over Na2SO4 and concentrated. The residue was purified by silica gel column chromatography to give that tile compound (3 g, 34%).
