실험 절차

To a solution of ethyl 2-isonicotinoyl-3-oxobutanoate (8.0 g) in ethanol (80 mL) was added hydrazine (1.7 g), and the mixture was stirred at room temperature for 1 hr, and poured into saturated aqueous sodium hydrogen carbonate solution. The mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (6.4 g).
