Versuchsvorschrift

To a solution of the crude product containing 3-amino-1-methylpiperidin-2-one hydrochloride obtained in C) and triethylamine (3 mL) in ethanol (15 mL) was added 4-thioxothiazolidin-2-one (666 mg) at room temperature. The reaction mixture was stirred at room temperature overnight, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (220 mg).
