Versuchsvorschrift

The compound of Example 38 (540 mg, 2.466 mmol) was dissolved in dioxan (12 ml) and water (8 ml). Lithium hydroxide hydrate (300 mg, 7.143 mmol) was added and the mixture stirred at 40° C. for 1 h. The mixture was acidified with acetic acid, evaporated, azeotroped with toluene and chromatographed on silica (eluant 60/40/2, v/v/v, EtOAc/hexanes/AcOH) to provide a colourless solid (450 mg, 90%).
