Procedure

The compound (150 mg) obtained in Example 34-3 was dissolved in DMF (3.0 ml) and then added with the compound (140 mg) synthesized in Example 2-2. To the mixture solution, HOBt (79.0 mg) and PS-carbodiimide (manufactured by Argonaut Technologies, Inc.) (681 mg) were added, followed by stirring at room temperature for 18 hours. After completion of the reaction, PS-carbodiimide was filtrated and DMF in the filtrate was then distilled off. The residue was added with chloroform and washed with a 1 mol/l sodium hydroxide aqueous solution and saturated saline solution. The residue was brought into an anhydrous state using anhydrous sodium sulfate and then concentrated. Subsequently, the concentrated product was purified through column chromatography (chloroform/methanol), thereby obtaining the subject compound (105 mg) as a white solid.
