The residue (300 mg, 0.78 mmol) is dissolved in methanol (6.85 ml), water (1.8 ml) and tetrahydrofuran (3.25 ml). To this reaction mixture is added aqueous lithium hydroxide solution (3.54 ml, 3.54 mol) The resulting mixture is stirred at room temperature overnight. The reaction mixture is diluted with dichloromethane/water. The organic layer is washed with citric acid, brine, dried over sodium sulfate and filtered. The solvent is removed in vacuo, and the residue is chromatographed by HPLC (0.01% trifluoroacetic acid in water/acetonitrile) to give the product as a yellow oil, 0.08 g (28% yield). MS: m/z 396.28 (M+1) The resulting reaction mixture The reaction mixture is evaporated in vacuo is stirred at room temperature overnight The organic layer is washed with citric acid, brine dried over sodium sulfate filtered The solvent is removed in vacuo the residue is chromatographed by HPLC (0.01% trifluoroacetic acid in water/acetonitrile)
