Reaction Steps
Acetic acid (1 mL) followed by iron (160 mg, 2.9 mmol) were added to a solution of 3-(4-[5-chloro-3-(4-nitrophenyl)-2-oxo-2H-pyridin-1-ylmethyl]phenyl}-propionic acid ethyl ester (0.31 g, 0.72 mmol) in ethanol (10 mL) and water (5 mL) with stirring. The mixture was then heated at reflux for 2 hours and allowed to cool to room temperature. After basification with aqueous ammonia the mixture was filtered through a pad of celite (Diatomaceous Earth) and the filtrate evaporated to dryness. The residue was taken up in aqueous sodium bicarbonate/ethyl acetate and the organic layer washed with brine, dried over anhydrous sodium sulfate, filtered and evaporated to dryness. After purification by chromatography on silica gel with a gradient of 30-50% ethyl acetate in hexane the title compound was obtained as an oil.
