Reaction Steps

A mixture of 6-methyl-2-pyridylmethanol (145 mg, 1.17 mmol) and sodium hydroxide (63 mg, 1.57 mmol) in benzene (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 sodium sulphate and concentrated under vacuum. The residue thus obtained was purified by column chromatography (70–80% EtOAc-Hexane) to afford the title compound E30 as a hygroscopic solid (257 mg, 70%). HPLC: Inertsil ODS 3V (250×4.6 mm) 5 microns [solvent A=0.01 M KH2PO4 (pH 7.0); solvent B=CH3CN], Gradient elution program: T/% B=0/60, 10/60, 25/80, 40/80, 45/60, 50/60; 268 nm, Rt 23.93 min, 99.14% purity; MS (CI): m/z 469 (M+, 100).
