Reaction Steps
The compound (289 mg) obtained in Example 23-4 was dissolved in anhydrous methanol (6.0 ml) and added with sodium cyanoborohydride (92.8 mg), acetic acid (1.00 ml), and acetaldehyde (61.3 μl). The whole was stirred overnight at room temperature under a nitrogen atmosphere. After completion of the reaction, the solvent was distilled off. The resultant was dissolved in chloroform and added with a 1 mol/l sodium hydroxide aqueous solution, followed by stirring for a while. The resultant was subjected to extraction with chloroform, washed with a saturated aqueous sodium hydrogen carbonate solution and a saturated saline solution. The organic layer was dried with anhydrous sodium sulfate. The solvent was distilled off, thereby obtaining the subject compound (311 mg) as a pale-yellow oily substance.
