Reaktionsschritte

Morpholine (80 μL, 0.83 mmol, 1.5 eq) is added at room temperature to a stirred solution of (1-thiiranylmethyl-piperidin-4-yl)-carbamic acid tert-butyl ester (300 mg, 0.55 mmol, 1.0 eq) in ethanol (2 mL). The reaction mixture is irradiated under microwave conditions for 4 minutes at 140° C. and 80 W and then solvent is evaporated to afford [1-(2-mercapto-3-morpholin-4-yl-propyl)-piperidin-4-yl]-carbamic acid tert-butyl ester as an off-white semisolid (266 mg, 67% yield).
