Procedure

A mixture of 4-hydroxypiperidine (0.198 g, 1.96 mmol) and sodium hydroxide (79 mg, 1.96 mmol) in benzene (10 mL) was heated to reflux for 2 hours with stirring under nitrogen atmosphere and then cooled to 25° C. followed by the addition of compound 133 (0.25 g, 0.65 mmol) at same temperature. The mixture was heated to reflux for 6 hours, concentrated under vacuum and diluted with water (10 mL). The precipitated solid was filtered off and purified by column chromatography (1–2% MeOH-CHCl3) to afford the title compound E24 as an off-white solid (0.20 g, 58%). mp 142–144° C.; HPLC: Hichrom RPB (250×4.6 mm) 5 microns [solvent A=0.01 M KH2PO4 (pH 5.5); solvent B=CH3CN], Gradient elution program: T/% B=0/20, 10/20, 25/80, 40/80, 55/60, 65/20, 70/20; 270 mn, Rt 40.56 min, 98.60% purity; MS (CI): m/z 447 (M+H, 100).
