Versuchsvorschrift

A flask containing N-(4'-iodophenyl)-2-amino octane (1.50 g, 4.5 mmol) was charged with acetic acid (15 ml) and acetic anhydride (15 ml). The reaction flask was immersed in an oil bath which was warmed to 70° C. over a period of 0.5 hr. After stirring for 19 hrs, the reaction was allowed to cool, diluted with ether (200 ml), washed with water (2×50 ml), saturated aqueous sodium bicarbonate (4×50 ml), water (2×50 ml) and brine (50 ml), dried (Na2SO4), filtered, and evaporated in vacuo. Flash column chromatography (silica, 1:4; EtOAc:hexanes) provided N-acetyl-N-2-octyl-4-iodoaniline (1.48 g, 70%) as a white solid. Mp 60°-62° C.
