Versuchsvorschrift

The compound (19.6 mg) obtained in Example 19-4 was dissolved in methanol (2.0 ml) and added with 1-methyl-2-imidazole carboxaldehyde (6.2 mg) and sodium cyanoborohydride (5.9 mg). The solution was adjusted to pH 4 with acetic acid and stirred at room temperature for 3 hours. The resultant was added with a saturated sodium hydrogen carbonate aqueous solution to stop the reaction and subjected to extraction with chloroform. The organic layer was washed with water and a saturated saline solution and dried with anhydrous sodium sulfate. The solvent was distilled off. The residue was purified through silica gel column chromatography (chloroform/ethyl acetate) and treated with hydrochloric acid, thereby obtaining a hydrochloride (22.0 mg) of the subject compound as a white solid.
