3-[(4,4,4-Trifluoro-3-oxo-1-butenyl)amino]-2-propenenitrile (a low-polar compound IIa; 1.90 g, 10 mmol) was dissolved in methanol (15 ml), and sodium hydoxide (600 mg, 15 mmol) was added. The mixture was heated under reflux for 6 hours. The reaction mixture was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (a eluting solvent: hexane/acetone=1/1) to obtain 1.25 g (yield 65.6%) of the title compound.
