実験手順

tert-butyl 2-(4-(hydroxymethyl)-5-oxo-2,5-dihydrofuran-3-yl)-1-oxo-2,8-diazaspiro[4.5]decane-8-carboxylate (0.42 g, 1.15 mmol), silver oxide (0.292 g, 1.26 mmol) and methyl iodide (0.358 mL, 5.73 mmol) were taken up in DCM (5 mL) and stirred over night at room temperature under nitrogen. Additional silver oxide (0.292 g, 1.26 mmol) and methyl iodide (0.358 mL, 5.73 mmol) were added to the mixture with DCE (8 mL) and the resulting mixture was heated at 54° C. overnight. The reaction mixture was filtered through CELITE® to remove silver oxide, concentrated, and purified by silica gel column chromatography (40 g RediSep Gold column) using (20-80) % EtOAc/DCM as mobile phase to afford the title compound.
