N-(2-Bromo-5-chloro-pyridin-3-yl)-4-chloro-N-methoxvmethyl-3-trifluoromethyl-benzenesulfonamide → 4-chloro-N-[5-chloro-2-(2-morpholin-4-yl-pyridine-4-carbonyl)-pyridin-3-yl]-N-methoxymethyl-3-trifluoromethyl-benzenesulfonamide

Participants

Reaction Steps

To a solution of N-(2-bromo-5-chloro-pyridin-3-yl)-4-chloro-N-methoxymethyl-3-trifluoromethyl-benzenesulfonamide (590 mg, 1.2 mmol) in THF (2 mL) was added isopropylmagnesium chloride (1.3 mL, 2.6 mmol) slowly at 0° C. One hour later, N-methoxy-N-methyl-2-morpholin-4-yl-isonicotinamide (300 mg, 1.2 mmol) was added and warmed up to RT while stirring overnight, quenched with water, extracted with ethyl acetate, concentrated and purified by flash column to give 4-chloro-N-[5-chloro-2-(2-morpholin-4-yl-pyridine-4-carbonyl)-pyridin-3-yl]-N-methoxymethyl-3-trifluoromethyl-benzenesulfonamide.
