実験手順

Using 2-hydrazino-5-methyl-1H-benzimidazole (4) obtained in Example 1, step 3 and ethyl 2-acetyl-3-(3,4-dichlorophenyl)propanoate (35), and by a method similar to that in Example 1, step 4, 4-[(3,4-dichlorophenyl)methyl]-3-methyl-1-(5-methyl-1H-benzimidazol-2-yl)-1H-pyrazol-5-ol (36) was obtained.
