실험 절차
To a solution of 3-fluoro-4-nitrobenzaldehyde (0.5 g, 2.96 mmol) and 2-(piperidin-4-yl)propan-2-ol (0.466 g, 3.25 mmol) in DCM (25 mL) was added AcOH (0.017 mL, 0.296 mmol) and sodium triacetoxyborohydride (0.689 g, 3.25 mmol), and the reaction was stirred at RT for 1 hour. After 1 hour, the reaction was quenched by the addition of 1 N aqueous NaOH (15 mL), and the layers were separated. The aqueous layer was extracted with DCM, and the combined organic layers were washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated. The residual product was adsorbed onto a plug of silica gel, and purified by column chromatography, eluting with 0-100% EtOAc in DCM, to provide 2-(1-(3-fluoro-4-nitrobenzyl)piperidin-4-yl)propan-2-ol as a yellow oil (0.75 g, 86% yield).
