To a solution of rac-(3S,4R)-[3-Amino-4-(3,4-dichloro-phenyl)-pyrrolidin-1-yl]-[1-(1-methyl-cyclopropanecarbonyl)-piperidin-4-yl]-methanone (120 mg, 0.28 mmol) in dichloromethane (1 mL) were added acetone (21 uL, 0.28 mmol) and sodiumtriacetoxy-borohydride (72 mg, 0.34 mmol) and acetic acid (16 uL, 0.28 mmol) and the reaction mixture was stirred at ambient temperature for 3 h. It was diluted with dichloromethane and washed with aqueous sodiumhydrogenecarbonate (1M). The organic layer was dried over sodium sulfate and concentrated affording the title compound (95 mg, 72%) as a light yellow foam. MS m/e: 466.3 [M]+.
