To a solution of the 2-(1-methyl-1H-imidazol-5-yl)cyclohex-2-en-1-one (80 mg, 0.454 mmol) prepared in Example 49a in methanol (2.0 mL), sodium borohydride (50 mg, 1.32 mmol) was added at room temperature, and the reaction solution was stirred at room temperature for 30 minutes. To the reaction solution, a saturated aqueous solution of ammonium chloride (20 mL) was added, followed by extraction with dichloromethane (50 mL). The thus obtained organic layer was dried over anhydrous sodium sulfate and vacuum concentrated to yield the title compound (50 mg, 61%) in the form of a trans/cis (2:1) mixture as a colorless oil.
