Add 24.4 g (0.154 mol) of p-fluorobenzoyl chloride in 100 mL of tetrahydrofuran dropwise to 17.88 g (0.154 mol) of N,N-diethylethylenediamine in 150 mL of tetrahydrofuran at 0° C. Stir at 0° C. for about 2 hr then at room temperature for about 17 hr. Concentrate the resultant solution and treat the residue with 1N NaOH until about pH=10. Extract the resultant solution with methylene chloride (2×100 mL). Dry the extract with Na2SO4 amd evaporate the solvent to give the title compound.
