Procedure

To a solution of 2,2,2-trifluoro-N-(morpholin-2-ylmethyl)-N-((1R,2S)-2-phenylcyclopropyl)acetamide (150 mg, 0.457 mmol) in 1,2-dichloroethane (DCE) (3 mL) were added ethyl 4-(3-oxopropyl)benzoate (113 mg, 0.548 mmol) and sodium triacetoxyborohydride (145 mg, 0.685 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, 20 to 100% EtOAc/hexanes) to give 200 mg or product as colorless oil.
