Versuchsvorschrift

A solution of 4-chloro-2-nitroaniline (34.5 g) in acetic acid (500 ml) was refluxed with iodine monochloride (65.0 g) for 7 h with stirring, then was cooled and added to excess water. The precipitate was filtered off, washed with aqueous sodium sulphite and after column chromatography yielded 4-chloro-2-iodo-6-nitroaniline (8.5 g). δ (360 MHz, DMSO-d6) 7.13 (2H, bs, NH2), 8.08 (1H, d, 3-H) and 8.13 (1H, d, 5-H).
