Versuchsvorschrift

The compound (278 mg) obtained in Example 2-2, HOBt (95.9 mg), and DCC (147 mg) were dissolved in anhydrous DMF (11.0 ml), followed by stirring at room temperature for 19 hours. Then, the solution was added with a solution (1.2 ml) of the compound (128 mg) obtained in Example 68-1 in DMF and stirred at room temperature for 20 hours. After completion of the reaction, the solvent was distilled off under reduced pressure. The residue was dissolved in chloroform and added with 1 mol/l hydrochloric acid to separate the solution into layers. The aqueous layer was added with a 1 mol/l sodium hydroxide aqueous solution to adjust the solution to pH 11. The aqueous layer was extracted with chloroform and the organic layer was then dried with anhydrous magnesium sulfate. After having been treated with hydrochloric acid, the product was purified through silica gel column chromatography (chloroform/methanol/water), thereby obtaining hydrochloride (10.2 mg) of the subject compound as a white solid.
