Participants

Reaction Steps

To a solution of methyl 4-((2,2,2-trifluoro-N-(trans-2-phenylcyclopropyl)acetamido)methyl)piperidine-4-carboxylate (108 mg, 0.281 mmol) in 1,2-dichloroethane (DCE) (2 mL) were added benzaldehyde (35.8 mg, 0.337 mmol) and sodium triacetoxyborohydride (95 mg, 0.450 mmol), and the mixture was stirred at room temperature for 18 h. The reaction was quenched with water (5 mL) and extracted with DCM (3×). The extract was dried (Na2SO4) and concentrated. The residue was purified using column chromatography (silica gel, 0 to 100% EtOAc/hexanes) to give 78 mg or product as colorless oil. MS: (M+H)+=475.3. 1H NMR (400 MHz, METHANOL-d4) δ ppm 1.42 (q, 1H), 1.53-1.76 (m, 3H), 2.08-2.34 (m, 4H), 2.42 (ddd, J=10.11, 6.44, 3.66 Hz, 1H), 2.78-2.99 (m, 2H), 3.13-3.24 (m, 1H), 3.53-3.65 (m, 5H), 3.70-3.86 (m, 2H), 7.10 (d, J=7.07 Hz, 2H), 7.18-7.25 (m, 1H), 7.27-7.40 (m, 7H).
