実験手順

50 mg (0.2 mmol) of the 1-amino-3-(4-carboxyphenyl)-2-thioxoimidazolidin-4-one synthesized above in 1) and 55 mg (0.22 mmol) of the 1-(3,4-dimethylphenyl)-5-hydroxy-3-methyl-1H-pyrazole-4-carbaldehyde synthesized in 1) of Reference Synthetic Example 1 were stirred in a liquid mixture of 10 ml of ethanol and 5 ml of methanol at room temperature for 96 hours. The resulting insoluble was collected by filtration to obtain 87 mg of the desired product as a yellow solid (yield 85%).
