3.4 g (0.008 mol) of pentafluoropropionyl bromide 2,4,6-trichlorophenylhydrazone and 0.8 g (0.008 mol) of N,N-diethylcyanamide were added to 20 ml of toluene. Then, 0.9 g (0.009 mol) of triethylamine was added thereto under stirring at room temperature. After completion of the dropwise addition, stirring was continued at room temperature for further 1 hour. Then, 20 ml of toluene was added thereto, followed by washing with water. The organic layer was dried, and the solvent was distilled off. The residue was purified by silica gel column chromatography to obtain 1.9 g (yield: 54.3%) of the desired compound as a brown powder. Melting point: 66°-70° C.
