Procedure

A mixture of thiomorpholine (97 mg, 0.942 mmol), sodium hydroxide (31.4 mg, 0.785 mmol) and water (0.5 mL) in 1,4-dioxane (15 mL) was heated to reflux for 3 hours with stirring under nitrogen atmosphere and then cooled to 25° C. followed by the addition of compound 133 (0.30 g, 0.785 mmol) at same temperature. The mixture was heated to reflux for 12 hours, concentrated under vacuum and diluted with water (20 mL). The mixture was then extracted with EtOAc (2×20 mL). The combined organic layers were washed with water (2×10 mL), dried over anhydrous Na2SO4 and concentrated under vacuum. The residue thus obtained was purified by column chromatography (10–20% EtOAc-Hexane) to afford the title compound E27 as a pale yellow solid (0.26 g, 74%). mp 78–80° C.; HPLC: Inertsil ODS 3V (250×4.6 mm) 5 microns [solvent A=0.01 M KH2PO4; solvent B=CH3CN], A:B=20:80; 220 nm, Rt 20.36 min, 97.15% purity; MS (CI): m/z 449 (M+H, 100).
