Procedure

To a solution of 4-carbamoyl-4-methyl-piperidine-1-carboxylic acid tert-butyl ester (2.1 g, 8.7 mmol) in THF (30 mL) was added Lawesson's reagent (3.5 g, 8.7 mmol) at room temperature. The mixture was heated at 50° C. for 3 hours. After cooling to room temperature, the solvent was removed in vacuo and the residue was partitioned between EtOAc and H2O. The organic layer was washed with saturated NaHCO3, and brine. After drying (Na2SO4), the solvent was removed in vacuo, and the residue was purified by silica column chromatography with EtOAc/hexanes to afford the desired product.
