DEPROTECTION OF 2-PYRIDYL SULFONYL GROUP FROM PYRIDINE-2-SULFONAMIDES BY MAGNESIUM IN METHANOL

Convenient deprotection of various pyridine-2-sulfonamides prepared by sulfonylation of primary and secondary amines with pyridine-2-sulfonylchloride was achieved by magnesium in methanol at 0°C to the corresponding amines in good yield.
