A mixture of (1E)-1-methoxy-4-methylpenta-1-en-3-one (508 mg, 3.96 mmol), 2-cyano-N-(4-fluorophenyl)acetamide (847 mg, 4.75 mmol), 1,4-diazabicyclo[2.2.2]octane (444 mg, 3.96 mmol) and 2-(2-methoxyethoxy)ethanol (10 mL) was stirred at 130° C. for 6 hr. After cooling to room temperature, the mixture was diluted with ethyl acetate, washed with 1N hydrochloric acid, water (×2) and saturated brine, dried over anhydrous magnesium sulfate and filtered. The solvent was evaporated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (ethyl acetate/hexane=0/100→60/40) and silica gel column chromatography (NH silica gel, ethyl acetate/hexane=0/100→60/40) to give the title compound (604 mg, 59%) as a yellow solid.
