Versuchsvorschrift

To a mixture of the compound obtained in Example 22 (3) (0.26 g), tetrahydrofuran (5 ml) and methanol (10 ml), a 1N aqueous sodium hydroxide solution (5 ml) was added at 15 to 30° C. and the mixture was stirred for 2 hours. 1N hydrochloric acid was added thereto and the mixture was extracted with dichloromethane. The organic layer was washed with water, dried over sodium sulfate and concentrated under reduced pressure to obtain 0.25 g of the desired product as a white crystal.
