Procedure

A mixture of 4-pyrrolidin-1-ylpiperidine (0.67 g) and sulfamide (0.46 g) were heated at 115° C. in dry 1,4-dioxane (30 ml) for 16 h. The solvents were evaporated in vacuo and the residue partitioned between EtOAc (containing a little methanol) and H2O. The organic phase was collected and the aqueous layer further extracted with EtOAc (×2). The combined organic phases collected, dried (MgSO4) and the solvent evaporated. The residue was triturated with Et2O and filtered to give the subtitle product as a beige solid. Yield: 0.43 g
