실험 절차

A solution of (3S,5R,6S)-3-((1H-tetrazol-5-yl)methyl)-5-(3-chlorophenyl)-6-(4-chlorophenyl)piperidin-2-one (Example 60, Step A) (65 mg, 0.162 mmol) in DMF (1.6 mL) was cooled to 0° C. and sodium tert-butoxide (31.1 mg, 0.323 mmol) was added. The reaction mixture was stirred at 0° C. for ten minutes before adding (bromomethyl)cyclopropane (78 μL, 0.808 mmol). The reaction mixture was warmed to room temperature and stirred for 16 hours, quenched with saturated ammonium chloride and diluted with water and ethyl acetate. The aqueous layer was extracted with ethyl acetate and the organic layers were combined, washed with 1M LiCl, sat. aq. NaCl solution, dried over sodium sulfate, and concentrated under reduced pressure. The residue was purified by reversed phase preparatory HPLC (column: Gemini-NX C18 5 um column; Phenomonex, Torrance, Calif.; eluent: 0 to 100% MeCN +0.1% TFA in water +0.1% TFA, over 20 minutes) to afford the title compound.
