Mode opératoire

To a solution of 3,5-dichloroanthranilic acid (7.89 g, 38.3 mmol) in methylene chloride (130 mL) at 0° C. was added triethylamine (18.6 mL, 134.0 mmol). A solution of 2-(3-chloro-pyridin-2-yl)-5-trifluoromethyl-2H-pyrazole-3-carbonyl chloride (13.7 g, 44.0 mmol) in methylene chloride (130 mL) at 0° C. was then added, the reaction allowed to warm to room temperature and then stirred further for 16 h. The reaction was concentrated in vacuo and used directly in the following reaction step.
