실험 절차
45 g of the compound of Example 2, 25.4 g of benzaldehyde and 300 ml of benzene are brought to reflux, removing the water formed. The mixture is evaporated to dryness, the residue is taken up with 300 ml of ethanol and 9 g of sodium borohydride are added portionwise, keeping the temperature at approximately 18° C. After one night at room temperature, the ethanol is removed under vacuum and the residue taken up with dilute hydrochloric acid solution. The acid phase is alkalinized and then extracted with ethyl ether. After evaporation of the solvent, the oil obtained is purified on a silica column using a mixture of methylene chloride and methanol (95:5 V/V) as elution solvent.
