Procedure

To a solution of 3-[3-(dimethylamino)prop-2-enoyl]-1-[3-(trifluoromethyl)phenyl]pyridazin-4(1H)-one (674 mg, 2.0 mmol) in ethanol (200 mL) were added 2-chlorophenylhydrazine hydrochloride (538 mg, 3.0 mmol) and Et3N (0.56 mL, 4.0 mmol). The mixture was stirred at 100° C. for 3 h and the solvent was removed under reduced pressure. Preparative HPLC chromatography provided 3-[1-(2-chlorophenyl)-1H-pyrazol-5-yl]-1-[3-(trifluoromethyl)phenyl]pyridazin-4(1H)-one as a pale yellow solid (280 mg, 34%).
