Versuchsvorschrift

The compound (69.5 mg) obtained in Example 102-5 was treated with an anion-exchange resin (Amberlite IRA-410), and the treated product was dissolved in anhydrous methanol (2.7 ml). The solution was added with a 36% formaldehyde aqueous solution (0.025 ml). Subsequently, the solution was added with sodium cyanoborohydride (20.7 mg) and adjusted to pH 5 with acetic acid, followed by stirring at room temperature for 20 hours. After the reaction, the solution was added with a 1 mol/l sodium hydroxide aqueous solution (1.0 ml), followed by extraction with chloroform. The extract was dried with magnesium sulfate. The solvent was distilled off. Then, the residue was purified through silica gel column chromatography (chloroform/methanol) and treated with hydrochloric acid, thereby obtaining hydrochloride (34.8 mg) of the subject compound as a white solid.
