실험 절차

47.2 90 mg (0.4 mmol) of 6-(3,4,5-trifluorophenyl)-2H-pyridazin-3-one and 111 mg (0.41 mmol) of methyl (E)-3-[2-(3-hydroxymethylphenyl)-pyrimidin-5-yl]acrylate are suspended in 3 ml of THF with 200 mg (0.6 mmol) of polymer-bound triphenylphosphine (about 3 mmol of triphenylphosphine per g), and the mixture is shaken at room temperature for 30 min. The mixture is cooled to 0° C., and 95 μl (0.6 mmol) of diethyl azodicarboxylate are added. The reaction mixture is shaken at room temperature for 24 h. The reaction mixture is purified by means of preparative
