Compound 17 (39 mg, 0.054 mmol) was dissolved in tetrahydrofuran (3.5 ml), water (1.75 ml) and methanol (1.75 ml). Lithium hydroxide (430 μl, 1 M in water) was then added and the reaction was stirred at room temperature for 24 h. The volume was reduced to half and water (10 ml) was added. Acidification (pH=5) followed by extraction with chloroform gave the pure title compound (34 mg, 90%). MS (M+H+) 700.2
