Reaction Steps

The compound (424.0 mg) obtained in Example 65-1 was dissolved in diethylene glycol (8.0 ml) and the whole was stirred at 80° C. for 3 days. After completion of the reaction, the resultant was added with chloroform and washed with water, followed by drying with magnesium 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 (280.2 mg) of the subject compound as a white solid.
