Versuchsvorschrift

The same operation as in Example (22b) was performed using benzyl cis(±)-(1-carbamothioyl-3-methoxypiperidin-4-yl)-carbamate obtained in Example (64b) (97 mg, 0.30 mmol) and ethyl 4-chloro-acetoacetate (60 μL, 0.44 mmol), to obtain 125.4 mg of the title compound as a colorless oily substance (96%).
