実験手順

The compound (171.8 mg) obtained in Example 112-2 was dissolved in anhydrous methanol (7.0 ml). The solution was added with 1-methyl-2-imidazole carboxaldehyde (65.0 mg) and sodium cyanoborohydride (49.0 mg). Then, the solution was adjusted to pH 5 with acetic acid and then stirred at room temperature for 2 days. After the reaction, the solvent was distilled off. The residue was added with a 1 mol/l sodium hydroxide aqueous solution and extracted with chloroform. The extract was dried with magnesium sulfate, and 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 (184.8 mg) of the subject compound as a white solid.
