Procedure

The compound (27.7 mg) obtained in Example 3-2 was dissolved in anhydrous methanol (1.1 ml). Then, the solution was added with a 36% formaldehyde aqueous solution (manufactured by Kanto Kagaku) (0.0160 ml) and sodium cyanoborohydride (13.2 mg) and adjusted to pH 5 with acetic acid, followed by stirring at room temperature for 22 hours. After completion of the reaction, the solvent was distilled off and the residue was then dissolved in chloroform, followed by washing with a 1 mol/l sodium hydroxide aqueous solution and saturated saline solution and drying with anhydrous magnesium sulfate. The solvent was distilled off and the residue was then treated with hydrochloric acid. Subsequently, the residue was purified through a solid-phase extraction column (Sep-Pack®, tC18, manufactured by Waters Corporation), thereby obtaining hydrochloride (16.4 mg) of the subject compound as a white solid.
