5 -Fluoro-2-iodonitrobenzene (17.4 g; 65.2 mmol) was dissolved in a
mixture of ethanol (100 mL) and acetic acid (12 mL) in a large RB flask
(at least 500 mL) equipped with an efficient condenser, and the stirred
mixture brought to a gentle reflux. Iron powder (26.6 g) was added,
followed immediately by iron(III) chloride hexahydrate (3 g). The
mixture was refluxed for a further 3 hours, then cooled and filtered
using a Buchner funnel (with the help, when necessary, of the addition
of ether or ethanol.)
To the filtrate was added ether (300 mL) and water (300 mL),
and the aqueous layer was repeatedly extracted with ether. The
combined organic layers were dried and concentrated, giving
5-fluoro-2-iodoaniline and a pure white solid (14.27 g; 92%).
