실험 절차
To a solution of ethyl 4-methylenecyclohexanecarboxylate (2 g, 11.89 mmol) in ether (40 mL) was added LAH (0.5 g, 13.17 mmol) portionwise under N2. The reaction mixture was refluxed for 1 h and was quenched by addition of 1 mL of EtOAc carefully and refluxed for 10 min. The reaction mixture was cooled down and added 3 mL of 1 N NaOH and stirred for 5 min, filtered off the solid and washed with ether. The filtration was washed with water, brine, dried (MgSO4), and removed the solvent to afford (4-methylenecyclohexyl)methanol.
