Versuchsvorschrift

After adding sodium triacetoxyborohydride (0.82 g, 3.85 mmol) to a solution of 4-(p-toluidino)piperidine (0.73 g, 3.85 mmol), N-[2-[1-(formylmethyl)cyclohexyl]ethyl]phthalimide (0.77 g, 2.57 mmol) and acetic acid (0.30 mL, 5.14 mmol) in 1,2-dichloroethane (10 mL), the mixture was stirred at room temperature for 1.5 hours. Saturated aqueous sodium hydrogencarbonate was then added, and extraction was performed with chloroform-ethanol (10:1). After drying (anhydrous sodium sulfate), the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (25 g Merck Art 9385, chloroform:methanol=20:1) to obtain the title compound as a colorless oil (1.32 g).
