실험 절차

To a cold (0° C.) stirred solution of 4-oxohomopiperidine.HCl (0.6 g, 4.05 mmol), K2CO3 (0.615 g, 4.46 mmol) in anhydrous THF (10 mL) will be ethyl chloroformate (0.44 mL, 4.05 mmol) dropwise. The reaction was warmed to RT for 2 hrs then quenched with H2O, extracted with EtOAc, and the organic layer dried over Na2SO4. Pure 1-ethylcarbonyl-4-oxohomopiperidine will be isolated via silica gel flash chromatography
