To a solution of 1-(3-bromo-4-methoxyphenyl)-1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-N-hydroxymethanimine (4.30 g, 10.4 mmol) and 2-[6-(bromomethyl)pyridin-2-yl]-1H-isoindole-1,3(2H)-dione (3.66 g, 11.5 mmol) in acetonitrile (40 mL) were added cesium carbonate (7.18 g, 22.0 mmol) and potassium iodide (174 mg, 1.05 mmol). After stirring overnight at room temperature, the reaction mixture was diluter with water (100 mL) and ethyl acetate (50 mL). After phase separation and further extraction of the aqueous phase with ethyl acetate (2×30 mL), the combined organic layers were dried over MgSO4 and concentrated in vacuo to afford 2-(6-{[({(3-bromo-4-methoxyphenyl)[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methylene}amino)oxy]methyl}pyridin-2-yl)-1H-isoindole-1,3(2H)-dione as an oil [7.10 g, yield 94%; HPLC/MS: m/z=646 (M+H); log P(HCOOH)=4.78].
