Procedure

To a solution of 2,2,2-trifluoro-N-(morpholin-2-ylmethyl)-N-((1R,2S)-2-phenylcyclopropyl)acetamide (100 mg, 0.305 mmol) in 1,2-dichloroethane (DCE) (2 mL) were added methyl 4-formylbenzoate (60.0 mg, 0.365 mmol) and sodium triacetoxyborohydride (97 mg, 0.457 mmol), and the mixture was stirred at room temperature for 18 h. The reaction was then quenched with water (5 mL) and extracted with DCM (3×). The extract was dried (Na2SO4) and concentrated. The residue was dissolved into methanol (3.00 mL) and sodium hydroxide (6M, 0.5 mL, 3.00 mmol) was added. The mixture was stirred at room temperature for 18 h and purified using reverse-phase HPLC. The fractions containing the product were combined, treated with 1N HCl and concentrated. The residue was dried under vacuum to give 81 mg of product (HCl salt) as white solid. MS: (M+H)+=367.2. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.16-1.36 (m, 1H), 1.50 (br. s., 1H), 2.93 (br. s., 2H), 3.10 (br. s., 2H), 3.35 (br. s., 2H), 4.05 (br. s., 2H), 4.36 (br. s., 2H), 7.10-7.39 (m, 5H), 7.74 (br. s., 2H) 8.01 (m, 2H).
