Procedure
The hydrochloride (190 mg) of the compound obtained in Example 65-1 was dissolved in DMF (5.0 ml) and added with N-(2-hydroxyethyl)-succinimide (57.8 mg) and the whole was refluxed under heating for 4 hours. After completion of the reaction, the solvent was distilled off. The resultant was dissolved in chloroform and added with a saturated aqueous sodium hydrogen carbonate solution and the whole was stirred for a while. The solution was subjected to extraction with chloroform and washed with a saturated saline solution. The organic layer was dried with anhydrous sodium sulfate. The solvent was distilled off. The residue was purified through silica gel column chromatography (chloroform/methanol) and treated with hydrochloric acid, thereby obtaining a hydrochloride (82.5 mg) of the subject compound as a pale-yellow solid.
