Procedure

To a solution of 2,2,2-trifluoro-N-(trans-2-(4-(1-methyl-1H-pyrazol-4-yl)phenyl)cyclopropyl)-N-(piperidin-4-ylmethyl)acetamide (85 mg, 0.209 mmol) in 1,2-dichloroethane (DCE) (2 mL) were added methyl 4-formylbenzoate (41.2 mg, 0.251 mmol) and sodium triacetoxyborohydride (75 mg, 0.356 mmol), and the mixture was stirred at room temperature for 18 h. The mixture was quenched with water (3 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 68 mg of product as off-white solid. MS: (M+H)+=555.3. 1H NMR (400 MHz, METHANOL-d4) δ ppm 1.28-1.53 (m, 4H), 1.56-1.76 (m, 3H), 1.80-1.96 (m, 1H), 1.98-2.11 (m, 3H), 2.44 (br. s., 1H), 2.75-2.97 (m, 3H), 3.09-3.19 (m, 1H), 7.12 (d, J=8.08 Hz, 2H), 7.41-7.55 (m, 5H), 7.91-8.03 (m, 3H)
