実験手順
A mixture of 0.41 g of the aldehyde(prepared as described in Reference Example 1), 8 ml of ethanol and 78 mg of sodium borohydride was stirred at room temperature for 30 minutes. The reaction mixture was diluted with ethyl acetate, washed with water, and a saturated aqueous solution of sodium chloride, dried over sodium sulphate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel using a 4% V/V solution of ethanol in chloroform as eluent to give 0.33 g of the title compound having the following physical characteristics:
