To a suspension of 4-bromo-3-chloro-5-(trifluoromethyl)aniline (15 g, 54.7 mmol, Eq: 1.00) in dichloromethane (13.2 g, 10.0 ml, 155 mmol, Eq: 25.3) at 0, was added 1,1′-thiocarbonyldiimidazole (11.7 g, 65.6 mmol, Eq: 1.2) The reaction was gradually warmed to room temperature and stirred overnight. The reaction was concentrated and chromatographed (220 g Redisep, 5 to 15% dichloromethane/hexane) to give 13.84 g (80%) pale yellow oil.
