Procedure

The compound (197.9 mg) obtained in Example 120-6 was dissolved in methanol (10 ml) and then added with 1-methyl-2-imidazole carboxaldehyde (68.0 mg) and sodium cyanoborohydride (64.7 mg). After that, the solution was adjusted to pH 5 with acetic acid, followed by stirring overnight at room temperature. After the solvent had been distilled off, the residue was purified through silica gel column chromatography (chloroform/methanol) and treated with hydrochloric acid, thereby obtaining hydrochloride (228.7 mg) of the subject compound as a white solid.
