Procedure
The hydrochloride (88.0 mg) of the compound obtained in Example 51-1 was added with 2-propanol (10 ml) and the whole was refluxed under heating for 2 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/ethyl acetate), thereby obtaining the subject compound (32.8 mg) as a colorless oily substance.
