Versuchsvorschrift

The compound (51.6 mg) obtained in Example 33-2, the compound (117 mg) obtained in Example 2-2, and HOBt (50.0 mg) were dissolved in anhydrous DMF (2.5 ml). Then, the solution was added with PS-carbodiimide (manufactured by Argonaut Technologies, Inc.) (373.1 mg), followed by stirring at room temperature for 17 hours. After completion of the reaction, the mixture was filtrated and the solvent was then distilled off. The residue was dissolved in chloroform and washed with a 1 mol/l sodium hydroxide aqueous solution and saturated saline solution. The residue was dried with anhydrous magnesium sulfate and the solvent was distilled off, followed by treatment with hydrochloric acid. The residue was purified through silica gel column chromatography (chloroform/methanol/water), thereby obtaining hydrochloride (18.5 mg) of the subject compound as a white solid.
