Reaction Steps

To a solution of 2-methyl-4-trifluoromethyl aniline (Step A) (2.2 g, 12.6 mmol) in chloroform (20 ml) at room temperature were added n-pentyl nitrite (2.2 g, 18.9 mmol) and iodine (6.38 g, 25.1 mmol). The mixture was heated to reflux for 1 h. The mixture was diluted with methylene chloride (50 ml). The solution was washed with saturated aqueous sodium thiosulfate, brine and dried over sodium sulfate. The title compound was obtained after flash column using hexane as the eluant.
