Versuchsvorschrift
The compound of Example 44, Step B (1.0 g, 2.055 mmole) was dissolved in THF (10 ml). To this solution was added 1N NaOH (4.1 ml). The reaction mixture was stirred at room temperature for two hours. Additional 1N NaOH was added and stirring continued for two hours. The THF solution was removed and the aqueous portion diluted with water and extracted with ether. The aqueous layer was acidified with concentrated HCl, extracted with chloroform, dried and evaporated. Trituration of the residue with ether/methanol afforded the title compound; m.p. 130°-132°.
