Procedure

The compound (120 mg) obtained in Example 2-2 was dissolved in anhydrous DMF (3.0 ml) and added with WSCI hydrochloride (103.3 mg) and HOBt (72.8 mg). Then, the solution was added with a solution of the compound (76.0 mg) obtained in Example 98-2 in DMF and stirred for 18 hours. After the reaction, the solvent was distilled off and the residue was then added with a 1 mol/l sodium hydroxide aqueous solution, followed by extraction with chloroform. The extract was washed with saturated saline solution and dried with magnesium sulfate, followed by distilling the solvent off. Subsequently, the residue was purified through silica gel column chromatography (chloroform/methanol) and then treated with hydrochloric acid, thereby obtaining hydrochloride (20.4 mg) of the subject compound as a white solid.
