Reaction Steps
To a suspension of pyridine-4-carbothioamide (2.9 g, 21 mmol) in ethanol (150 mL) was added ethyl 2-bromo-3-oxo-3-phenylpropanoate (5.9 g, 22 mmol), and the mixture was heated under reflux for 8 hr. The reaction solution was allowed to cool to room temperature, and the solid was collected by filtration, washed with diethyl ether, dried, suspended in ethyl acetate (250 mL), and washed with saturated aqueous sodium bicarbonate solution (150 mL×2). The combined aqueous layer was extracted with ethyl acetate (100 mL×2). The combined organic layer was dried over anhydrous magnesium sulfate, the insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The residue was washed with diethyl ether, and collected by filtration to give the title compound (3.7 g, 57%) as a colorless solid.
