Versuchsvorschrift
A suspension of 2-bromo-1-ethyl-3-nitrobenzene (9.2 g, 40 mmol) in EtOH (100 mL) in concentrated hydrochloric acid (0.17 mL, 2 mmol) was refluxed for 2 hours. The mixture was subsequently purified by column chromatography, eluting with petroleum ether to give the title compound as a red oil (6.5 g, 81%). 1H NMR (400 MHz, CDCl3) δ 7.03 (1H, dd, J=7.6, 8.0 Hz), 6.64-6.62 (2H, m), 2.73 (2H, q, J=7.6 Hz), 1.22 (3H, t, J=7.6 Hz).
