반응 단계

To a suspension of lithium aluminum hydride (2.6 g, 69 mmol) in diethyl ether (160 mL,) was added slowly a solution of commercially available ethyl 4,4-difluorocyclohexanecarboxylate (Matrix, 11.0 g, 57 mmol) in diethyl ether (20 mL). The reaction mixture was refluxed for 4 hours, then cooled in an ice bath, quenched cautiously with sequential addition of water (2.6 mL.), 15% NaOH (2.6 mL) and water (7.8 mL) and extracted with ethyl acetate (3×100 mL). The mixture was filtered and concentrated to afford the title compound.
