Reaction Steps
To a mixture of ethyl 2-(1-ethoxyvinyl)nicotinate (27 g) and acetone (300 mL) was added 2M hydrochloric acid (370 mL), and the mixture was stirred overnight at room temperature. The solvent was evaporated under reduced pressure, to the residue were added ethyl acetate and saturated aqueous sodium hydrogen carbonate solution, and 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 (15 g).
