Procedure

A solution of 1-methyl-4-(methylamino)piperidine (2.6 g) and sulfamide (4.0 g) in 1,4-dioxane (30 ml) was heated at 110° C. for 18 h. The reaction mixture was cooled, the solvent evaporated under reduced pressure and the residue dissolved in water. The aqueous solution was extracted with EtOAc which was washed with a small volume of saturated aqueous brine, dried (MgSO4) and the solvent evaporated under reduced pressure to give the subtitle product as a pale yellow solid. Yield: 1.5 g
