Reaction Steps

2-iodo-4-(trifluoromethyl)aniline was prepared according to method D Step I with iodine (1.58 g; 6.21 mmol), silver sulphate (1.94 g; 6.21 mmol) and 4-(trifluoromethyl)aniline (0.8 mL; 6.21 mmol) in ethanol (40 mL). The crude residue was purified by flash chromatography on silica gel (eluent 2 to 40% ethyl acetate in heptane) to afford 1.08 g (61%) of 2-iodo-4-(trifluoromethyl)aniline as a red oil.
