Procedure

The compound (199 mg) obtained in Example 43-1 was dissolved in methanol (6 ml) and then added with 2-imidazole carboxaldehyde (57.1 mg) and sodium cyanoborohydride (65.4 mg). The reaction solution was adjusted to pH 5 with the addition of acetic acid, followed by stirring at room temperature for 14 hours. The reaction solution was added with a 1 mol/l sodium hydroxide aqueous solution and then extracted with chloroform. Then, the organic layer was washed with saturated saline solution and dried with anhydrous sodium sulfate. After the solvent had been distilled off, the residue obtained was purified through silica gel column chromatography (chloroform/methanol) and treated with hydrochloric acid, thereby obtaining hydrochloride (231 mg) of the subject compound as a yellow solid.
