Versuchsvorschrift

(1R,2S)-2-phenylcyclopropanamine (1.051 g, 7.89 mmol), ethyl 4-(3-(4-formylpiperidin-1-yl)propyl)benzoate (1.9 g, 6.26 mmol) in methanol (50 mL) were heated to reflux for 5 minutes. The reaction was cooled to room temperature and added sodium cyanoborohydride (0.590 g, 9.39 mmol). The reaction was stirred at room temperature for 16 hours. The reaction was concentrated and DCM was added and washed with water, brine, dried over MgSO4, filtered and rotovapped off solvent. The residue was purified via Biotage (0% to 100% EtOAc:Hex; to get off ethyl 4-(3-(4-(cyano(((1R,2S)-2-phenylcyclopropyl)amino)methyl)piperidin-1-yl)propyl)benzoate then 0% to 20% MeOH:DCM to get off ethyl 4-(3-(4-((((1R,2S)-phenylcyclopropyl)amino)methyl)piperidin-1-yl)propyl)benzoate 50 g-HP—silica gel column).
