Reaction Conditions

Reaction Steps

To a stirred solution of 2-bromo-5-fluorotoluene (1.495 g, 7.909 mmol, Aldrich, used as received) in conc. H2SO4 (10.0 mL) at 0° C., KNO3 (0.800 g, 7.91 mmol) was added in one lot. The resulting pale yellow solution was warmed to 28° C. and stirred overnight at 28° C. It was then poured into ice (50 g) and extracted with ethyl acetate (75 mL). The ethyl acetate was dried over anhydrous Na2SO4, removed under vacuum, and the resulting oil dried further under vacuum to afford 1.832 g (98%) of the title compound as an oil; 1H NMR (CDCl3): δ 2.495 (s, 33H), 7.213 (d, 1H, J1 =11.4 Hz), 8.268 (d, 1H, J1 =7.2 Hz).
