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 2-phenoxy-ethanesulfonyl chloride (21.14 mg, 96 μmol, 1.1 eq). The product was purified by preparative TLC, the plate was eluted with dichloromethane/methanol 95/5, to give N-(5-(3-chloro-4-cyanophenyl)pyridin-3-yl)-2-phenoxyethanesulfonamide (8.1 mg, >95% purity, yield: 22.5%).
