Reaktionsschritte

To a refluxing well-stirred suspension of iron powder (19.6 g, 100 mesh) in ethanol (60 mL), water (13.4 mL) and 36% hydrochloric acid (1.4 mL) was added 1-chloro-2-(3-methyl-2-butenyloxy)-4-nitrobenzene (24 g) in portions over 15-30 minutes. After 3 hours thin-layer chromatography (TLC) (ethyl acetate:hexane, 40:60) showed no substrate. The reaction mixture was then filtered hot and the iron oxide filter cake was washed with hot ethanol. The combined ethanol washes were evaporated to produce a residue. The residue was taken up in diethyl ether, washed with aqueous bicarbonate and water, dried (MgSO4), filtered, and evaporated, to give 4-chloro-3-(3-methyl-2-butenyloxy)benzenamine, 19.8 g of light brown oil.
