Reaktionsschritte

The compound (104.9 mg) obtained in Example 47-3 was dissolved in methanol (3.2 ml) and then added with quinoline-4-aldehyde (47.2 mg) and sodium cyanoborohydride (31.4 mg). Then, the solution was adjusted to pH 5 with acetic acid and then stirred at room temperature for 14 hours. After completion of the reaction, a 1 mol/l sodium hydroxide aqueous solution was added to the reaction solution, followed by separation/extraction with chloroform. The organic layer was dried with anhydrous sodium sulfate and the solvent was then distilled off. The residue was purified through silica gel column chromatography (chloroform/ethyl acetate) and then treated with hydrochloric acid, thereby obtaining hydrochloride (76.4 mg) of the subject compound as a white solid.
