실험 절차
A solution of ethyl 4-(4-benzamidopiperidin-1-yl)benzoate (4.2 g, 11.9 mmol) in THF (400 mL) was cooled to 0° C. under nitrogen and treated with DIBAL-H (1.0 M in THF, 47 mL, 47 mmol). The mixture was warmed to room temperature and stirred for 1 hour. Then, the reaction mixture was quenched with Rochelle's salt (10% aqueous), concentrated to remove the THF, brine (300 mL) was added, and the organic phase was extracted with CH2Cl2 (3×200 mL), dried over anhydrous MgSO4, filtered, and concentrated, to afford N-(1-(4-(hydroxymethyl)phenyl)piperidin-4-yl)benzamide as a yellow solid that was used without further purification.
