Procedure

Added sodium triacetoxyborohydride (180 mg, 0.850 mmol) to a solution of 2,2,2-trifluoro-N-((trans)-2-phenylcyclopropyl)-N-(piperidin-4-ylmethyl)acetamide (185 mg, 0.567 mmol), N-(4-formylphenyl)methanesulfonamide (124 mg, 0.624 mmol) in 1,2-Dichloroethane (DCE) (40 mL). Let stir at RT for 16 hours. Added 100 mg of sodium triacetoxyborohydride and let stir at RT for 16 hours. Concentrated on a rotovap. Added water and extracted with DCM. Combined DCM extracts and washed with brine, dried over MgSO4, filtered and rotovapped off DCM. The residue was purified via Biotage (0% to 100% EtOAc:Hex then 0% to 20% MeOH:DCM 25 g-HP-silica gel column). Obtained 210 mg. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.47 (br. s., H), 1.90 (br. s., 4H), 2.08-2.27 (m, 3H), 2.39 (br. s., 1H), 2.65 (s, 1H), 3.04 (br. s., 4H), 3.23-3.76 (m, 3H), 4.14 (br. s., 2H), 6.99-7.15 (m, 2H), 7.2-7.3 (m, 3H), 7.46 (br. s., 23H), 7.63 (br. s., 2H), 9.05 (br. s., 1H), 11.69 (br. s., 1H)
