Procedure
The compound of Step C above, (800 mg, 1.54 mmoles, 1N NaOH (3.2 ml), water (3.2 ml) and THF (10 ml) were stirred at room temperature for three hours. The THF layer was removed and the aqueous portion diluted with water and extracted with ether. The aqueous portion was acidified with concentrated HCl. A solid precipitate formed which was extracted into ether, dried and concentrated. Trituration of the residue with ether-methanol afforded the title compound; mp 138°-140°.
