Procedure

To a stiffed solution of 2,5dichloro-1-ethylbenzene (0.795 g, 4.68 mmol) in coned H2SO4 (4.5 mL) at 0° C., KNO3 (0.473 g, 4.68 mmol) was added in one portion. The resulting pale yellow solution was allowed to warm to room temperature and was stirred overnight at room temperature. It was then poured into ice (80 g) and extracted with ether (3×30 mL). The ether was dried over anhydrous Na2SO4, removed under vacuum, and the resulting oil was dried further under vacuum to obtain 0.943 g (92%) title compound as an oil; 1H NMR (CDCl3) δ 1.27 (t, 3H, J=7.5 Hz), 2.80 (q, 2H, J=7.5 Hz), 7.42 (s, 1H), 7.94 (s, 1H).
