Reaction Steps

After adding acetonitrile (100 mL) and ethoxymethylenemalononitrile (4.5 g) to N-(2-aminoethyl)(4-fluorophenyl)carboxamide hydrochloride (8.3 g), a solution of triethylamine (4.5 g) in acetonitrile (20 mL) was added thereto. After stirring at room temperature for 15 minutes, the solvent was distilled off under reduced pressure, water and ethyl acetate were added to the residue, and the mixture was stirred. The precipitated solid was filtered out to obtain the crude title compound (6.5 g) as a brown solid.
