実験手順
To a 0° C. solution of tert-butyl 4-(2,4-difluorobenzoyl)piperidine-1-carboxylate (1.28 g, 3.93 mmol) in MeOH (15.7 mL) was added NaBH4 (0.372 g, 9.84 mmol). The ice bath was removed and the reaction mixture stirred for 2 h at room temperature then was quenched with saturated aqueous NH4Cl. The organic layer was extracted with EtOAc, washed with H2O and dried over MgSO4. The solvent was removed under reduced pressure gave tert-butyl 4-((2,4-difluorophenyl)(hydroxy)methyl)piperidine-1-carboxylate as a white hygroscopic solid.
