Procedure

The compound (1.04 g) obtained in Example 61-2 was dissolved in DMF (31.2 ml) and added with 60% sodium hydride (0.166 g) and 1-iodopropane (0.405 ml) while the whole was being stirred under ice-cooling. The solution was warmed to room temperature and stirred for 15 hours. The reaction solution was poured in ice-cold water and subjected to separation/extraction with chloroform. The organic layer was washed with a saturated saline solution and then dried with anhydrous sodium sulfate, followed by concentration under reduced pressure. The residue was again dissolved in a 4 mol/l hydrogen chloride/dioxane solution (10 ml) and the whole was stirred at room temperature for 1 hour. The reaction solution was concentrated under reduced pressure. The residue was dissolved in chloroform and washed with a 1 mol/l sodium hydroxide aqueous solution and a saturated saline solution. Then, the resultant was dried with anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified′through silica gel column chromatography (chloroform), thereby obtaining the subject compound (451.8 mg) as a yellow oily substance.
