Participants

Reaction Steps

To a solution of 2,2,2-trifluoro-N-((1R,2S)-2-phenylcyclopropyl)-N-(piperidin-4-ylmethyl)acetamide (120 mg, 0.368 mmol) in 1,2-dichloroethane (DCE) (2 mL) were added 2-(4-formylphenyl)acetic acid (72.4 mg, 0.441 mmol) and sodium triacetoxyborohydride (125 mg, 0.588 mmol), and the reaction mixture was stirred at room temperature for 18 h. The mixture was quenched with water (2 mL) and extracted with DCM (3×). The extract was dried (Na2SO4) and concentrated. The residue was dissolved in methanol (2.000 mL) and sodium hydroxide (1M, 2 mL, 2.000 mmol) was added. The mixture was stirred at room temperature for 3 h and concentrated. The residue was treated with methanol and filtered. The filtrate was purified using reverse-phase HPLC under the acidic conditions. The fractions containing product were combined, treated and concentrated. The residue was further dried under vacuum to give 54 mg of product (HCl salt) as off-white solid. MS: (M+H)+=379.3. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.20-1.34 (m, 1H), 1.51-1.70 (m, 3H), 1.87-2.13 (m, 3H), 2.56-2.66 (m, 1H), 2.83-3.15 (m, 5H), 3.32 (br. s., 2H), 4.16-4.44 (m, 2H), 7.12-7.43 (m, 7H), 7.45-7.61 (m, 2H).
