실험 절차

To a stirred solution of 4-{4-[7-(4-cyano-3-trifluoromethylphenyl)-8-oxo-6-thioxo-5,7-diazaspiro[3.4]oct-5-yl]-phenyl}-butyric acid methyl ester (67) [ND-4] (61 mg, 0.12 mmol) in dichloromethane (5 mL), 1M diisobutylaluminum hydride (DIBAL) solution in hexane (0.16 mL, 0.16 mmol) was added at −78° C. After 30 min, the reaction mixture was quenched with saturated Rochelle's salt solution. The resulting mixture was stirred at 21° C. until both phases were clearly separated and the organic layer was clear. After extraction, the separated organic layer was dried over MgSO4, filtered, and concentrated under vacuum. The crude mixture of (66) and (68) was purified by flash column chromatography (hexane:ethyl acetate,
