Reaction Steps

To a stirred solution of N-(2-bromo-5-chloro-6-methyl-pyridin-3-yl)-4-chloro-N-methoxymethyl-3-trifluoromethyl-benzenesulfonamide (255 mg, 0.5 mmol) in anhydrous THF (3 mL) was added 2 M isopropylmagnesiumchloride in THF (600 μL, 1.2 mmol) at −40° C. It was then warmed to 0° C. and stirred at the same temperature for 1 h and then N-Methoxy-N-methyl-2-methylsulfanyl-benzamide (422 mg, 1.00 mmol) was added in and the progress of the reaction was followed by LCMS. The reaction mixture was warmed to room temperature and stirred overnight (18 h). It was then quenched with saturated aqueous NH4Cl (2 mL), and extracted with EtOAc. The combined extracts were dried (Na2SO4), filtered and concentrated under reduced pressure. The residue was purified by flash column chromatography (ISCO) to provide 4-chloro-N-[5-chloro-6-methyl-2-(2-methylsulfanyl-benzoyl)-pyridin-3-yl]-N-methoxymethyl-3-trifluoromethyl-benzenesulfonamide. Mass spectrum m/z: 601.4 (M+Na).
