Procedure
A stirred mixture of 15.61 g of 3-fluoro-4-methoxyaniline and of 24.25 g of diethyl ethoxymethylenemalonate is brought to 100° C. for 2.5 hours. After cooling to ambient temperature and then evaporation to dryness at 50° C. under reduced pressure, 35 g of diethyl 2-[(3-fluoro-4-methoxyphenylamino)methylene]malonate are obtained, in the form of a beige solid which melts at 63° C.
