Procedure

To a suspension of the compound obtained in Example 6 (2) (1.10 g) in methanol (24 ml), a 1N aqueous potassium hydroxide solution (4.8 ml) was added and the mixture was stirred at 15 to 30° C. for 1 hour. The mixture was further heated under reflux for 15 minutes. After completion of the reaction, the reaction solution was poured into water, extracted with chloroform, washed with a saturated aqueous NaCl solution, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue was washed with methanol/water and filtered off. Further, the insoluables in the aqueous layer during extraction were filtered off, and they were combined and heated to dryness to obtain 417 mg of the desired product as a white powder.
