To 10 ml of condensed methylamine was added 1.86 g (10 mmol) of 6-fluoropyridine-2-sulfonamide. The mixture was allowed to reflux under a dry-ice condenser for 4 hr, then excess amine was allowed to evaporate overnight. The residue was crystallized with water to yield 1.64 g of tan solid, m.p. 124° C. to 26° C.
