実験手順
Water (1 mL) was added to a cod solution of 4-(3-pyridyl)cyclohexanone ethylene acetal (4.79 g, 21.9 mmol) in CF3CO2H (20 mL). After stirring room temperature for 6 h, the reaction mixture was added dropwise to sat. NaHCO3. aq. The resulting mixture was adjusted to pH 8 with 2M NaOH aq. and extracted with CH2Cl2, After drying and consentration, the crude product was purified by column chromatography (Hexane/EtOAc=1/1→0/1) to yield 4-(3-pyridyl)cyclohexanone (3.23 g, 84%) as a colorless powder.
