Participants

Reaction Steps

To a solution of 3-Thiocarbamoyl-piperidine-1-carboxylic acid tert-butyl ester (2.2 g, 9.02 mmol) in acetone (45 mL) was added 1,3-dichloroacetone (1.49 g, 11.7 mmol), MgSO4 (1.63 g, 13.5 mmol) and MgCO3 (0.76 g, 9.02 mmol). The mixture was heated under reflux overnight, cooled and filtered through celite. The solvent was removed in vacuo and the residue was redissolved with EtOAc (20 mL). The resulting solution was washed successively with 5% NaHSO3, saturated NaHCO3, and brine. After drying (Na2SO4), the solvent was removed to afford the desired product which was used without further purification.
