Procedure

The compound (104 mg) obtained in Example 47-3 was dissolved in methanol (5.0 ml) and added with 3-ethoxy-2-pyridine aldehyde (74.7 mg) synthesized by the method described in Marsais, F et al, Synthesis, 235 (1982), followed by the addition of sodium cyanoborohydride (46.6 mg). After that, the reaction solution was adjusted to about pH 5 with acetic acid and then stirred at room temperature for 65 hours. The reaction solution was added with a saturated aqueous sodium bicarbonate solution and then extracted with chloroform. The organic layer was washed with saturated saline solution and then dried with anhydrous sodium sulfate. Subsequently, the solvent was distilled off. The resulting crude product was purified through silica gel column chromatography (chloroform/methanol) and then treated with hydrochloric acid, thereby obtaining hydrochloride (132 mg) of the subject compound as a white solid.
