Procedure

Tert-butylamine (6.2 mL, 84.7 mmoles) was added to a solution of 13.15 g (43.5 mmoles) of 3-(2,4,5-trifluorophenyl)-3-oxo-2-(ethoxymethylene)-propanoic acid ethyl ester in 19 mL of dry ethanol at -15° C. After 5 minutes, the mixture was stirred at room temperature for one hour, and then concentrated to dryness. The crude residue (10.87 g) was crystallized from 25 mL of hexane to afford 7.22 g of titled compound.
