Procedure

A mixture of 6-chloropyridine-3-sulfonamide (5 g, 0.0259 mol) and aqueous dimethylamine (100 ml, 40%) is stirred at rt for 13 h. The mixture is concentrated to ⅕th of its original volume and cooled. The precipitate is collected by filtration, washed with ice-cold water (10 ml) and dried under vacuum to afford 4.5 g (95%) of the title compound as a solid. mp: 133-138° C., LC/MS: (ES+) 201.9.
