実験手順

800 mg of the compound of Example 5 was dissolved in 20 ml of ethanol, 140 mg (2 equivalents) of sodium borohydride was added under ice cooling, then the result was agitated at room temperature for 10 minutes. Water was added and extraction was performed with ethyl acetate. The organic layer was washed with water and saturated saline, then was dried with anhydrous magnesium sulfate. The solvent was distilled off and the resultant crude product was refined with silica gel column chromatography (methylene chloride:methanol=30:1), to obtain the above-referenced compound in an amount of 600 mg (yield of 81%).
