Versuchsvorschrift

The compound (57.7 mg) obtained in Example 32-2 was dissolved in methanol (1.73 ml) and then added with 4-heptanone (manufactured by Tokyo Kasei Kogyo Co., Ltd.) (30.7 μl), sodium cyanoborohydride (13.8 mg), and triethylamine (76.5 μl). The solution was adjusted to pH 5 with acetic acid and stirred at room temperature for 7 days. The reaction solution was added with a 1 mol/l sodium hydroxide aqueous solution and then the whole was separated and extracted with chloroform. The organic layer was dried with anhydrous sodium sulfate. The solvent was distilled off and the residue was then purified through silica gel column chromatography (chloroform/methanol) and treated with hydrochloric acid, thereby obtaining hydrochloride (27.7 mg) of the subject compound as a pale-yellow solid.
