실험 절차

A mixture of 2,4-dichloroacetophenone (378 mg, 2.0 mmol), p-chloro-phenylhydrazine (358 mg, 2.0 mmol and polyphosphoric acid (PPA) (0.5 mL) is heated at 100° C. for 8 h, cooled to room temperature, diluted with water, stirred briefly, allowed to stand at room temperature for 16 h and filtered. The filtercake is washed with water and air-dried to afford the title compound, 320 mg (54% yield), identified by NMR and mass spectral analyses.
