  名称：

  Synthesis of 2-Aryl-4-(R-sulfanylmethyl)-3-methyl-6,7-dihydro-2H-pyrazolo[3,4-d]pyridazin-7-ones

  摘要：

  Bromination of ethyl 1-aryl-4-acetyl-5-methyl-1H-pyrazole-3-carboxylates gave ethyl 1-aryl-4-(bromoacetyl)-5-methyl-1H-pyrazol-3-carboxylates which were used to alkylate benzenethiol and heterocyclic thiones at the sulfur atom. Reactions of the resulting S-alkylation products with hydrazine or methylhydrazine involved closure of pyridazine ring to afford 2-aryl-3-methyl-4-[phenyl(or hetaryl)sulfanylmethyl]-6,7-dihydro-2H-pyrazolo[3,4-d]pyridazin-7-ones.
