実験手順
To a stirred solution of 3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (Aldrich, 15.99 g, 87.28 mmol) in methylene chloride (600 mL) at 0° C., mCPBA (Aldrich, 29.4 g, 77%, 131 mmol) was added and the mixture was stirred overnight. The reaction was quenched with 10% Na2S2O3 and the organic layer was separated and washed with 5% sodium carbonate, brine and water and dried over sodium sulfate and concentrated to give a light yellow oil, which was chromatographied (10% EtOAc/Hexane) to yield a colorless oil. 14.93 g. The compound was used directly for the next step.
