Reaction Steps
A mixture of 2.55 g of 4-chloro-1-nitro-2-(propan-2-yloxy)benzene in 40 ml of acetic acid is heated at 50° C., and then 7 ml of water and 2.64 g of iron powder are added. The mixture is stirred for 1 h at 50° C., and then cooled to ambient temperature and filtered on Celite. The Celite is rinsed three times with 20 ml of methanol, and the filtrate is concentrated under reduced pressure. The residue is taken up in 50 ml of 1N sodium hydroxide and 50 ml of dichloromethane. The aqueous phase is extracted twice with 50 ml of dichloromethane. The combined organic phases are dried over anhydrous magnesium sulfate, filtered and then concentrated to dryness under reduced pressure, so as to obtain 2.25 g of 4-chloro-2-(propan-2-yloxy)aniline in the form of a green oil.
