摘要：

3-(Bromoacetyl)tropolone was reacted with five 2-mercaptobenzimidazoles to give 3-[[(2-benzimidazolyl)thio]acetyl]tropolones. These products were heated with methylhydrazine to afford 3-[[(2-benzimidazolyl)thio]methyl]-1-methyl-1,8-dihydrocycloheptapyrazol-8-ones. hydrocycloheptapyrazol-8-one was isolated as a minor product.
