Participants

Reaction Steps

According to General Sulfonylation Procedure 2 in Example 1, to a solution of 4-(5-amino-pyridin-3-yl)-2-chloro-benzonitrile (20 mg, 87 μmol, leg) in anhydrous pyridine (500 μl) was added 4-methoxy-benzenesulfonyl chloride (19.8 mg, 96 μmol, 1.1 eq). The crude product was purified by Isco Cornbiflash® Companion™ flash chromatography system on normal phase (4 g SiO2, flow rate 18 mL/min), eluting with mixtures of dichloromethane/methanol, to give N-[5-(3-chloro-4-cyano-phenyl)-pyridin-3-yl]-4-methoxy-benzenesulfonamide (15 mg, >95% purity, yield: 43%).
