Reaction Steps

4-amino-3-bromo-N-[2-ethyl-6-methyl-4-(1,1,1,2,3,3,4,4,4-nonafluorobutan-2-yl)phenyl]benzamide (0.254 g) was dissolved in tetrahydrofuran (20 ml). To the mixture was added 4,5-dichloro-1,2,3-dithiazol-1-ium chloride (0.106 g), and stirred at room temperature for 2 hours. To the reaction mixture was added pyridine (0.091 g) in dichloromethane, and stirred at room temperature for 1 hour. The solvent was removed under reduced pressure. To the residue was added water and extracted twice with ethyl acetate. The organic phases were combined and washed with water, and dried over anhydrous magnesium sulfate. The drying agent (anhydrous magnesium sulfate) was removed by filtration and the solvent was distilled off under the reduced pressure. The residue was purified by column chromatography to obtain 3-bromo-4-{[4-chloro-5H-1,2,3-dithiazol-5-ylidene]amino}-N-[2-ethyl-6-methyl-4-(1,1,1,2,3,3,4,4,4-nonafluorobutan-2-yl)phenyl]benzamide (0.270 g, 85%).
