Reaction Steps

To a solution of the 2-amino-N-(bis-2-propyl-λ4-sulfanylidene)-3,5-dichloro-benzamide (26.2 g, 81.6 mmol) and potassium carbonate (12.4 g, 89.7 mmol) in toluene (80 mL) was added N,N-dimethylaminopyridine (0.50 g, 4.1 mmol). The reaction was then heated to 50° C. and 2-(3-chloro-pyridin-2-yl)-5-trifluoromethyl-2H-pyrazole-3-carbonyl chloride (32.3 g, 93.8 mmol) was added dropwise. After stirring for 2 h at this temperature water was added (50 mL) and the reaction stirred for a further 15 min, then cooled to 0° C. and stirred for a further 30 min. The resulting solid was filtered and washed with water and toluene (minimal) to afford the title compound (32.0 g, 66%).
