Procedure

To a suspension of potassium carbonate (8.08 g, 58.5 mmol, 1.50 equiv) and 2-amino-3,5-dichloro-N-(diethyl-λ4-sulfanylidene)benzamide (11.43 g, 38.98 mmol) in acetonitrile (100 mL) was added a solution of 2-(3-chloro-2-pyridyl)-5-(trifluoromethyl)pyrazole-3-carbonyl chloride (15.8 g, 43.31 mmol, 1.10 equiv.) in acetonitrile (50 mL) at room temperature. After 6 h at this temperature, the solids were filtered off. The resulting filtrate was washed with water and dried over Na2SO4. After filtration, the filtrate was concentrated in vacuum and the resulting solids were crystallized from diisopropyl ether to yield the title compound (19.53 g, 88%).
