Reaction Steps
3-[(4,4,4-Trifluoro-3-oxo-1-butenyl)amino]-2-propenenitrile (a mixture of IIa and IIb; 1.90 g, 10 mmol) was dissolved in methanol (20 ml), and potassium carbonate (2.10 g, 15 mmol) was added. The mixture was heated under reflux for 2 hours. The reaction solution was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (a eluting solvent: hexane/ethyl acetate=3/1) to obtain 653 mg (yield 32.7%) of the title compound.
