4-(Aryloxyalkyl)pyrazoles of the formula ##STR1## useful as antiviral agents, are prepared by reacting the corresponding diketones of the formula Ar--O--Alk--CH(COR')COR" with hydrazine or a substituted hydrazine H.sub.2 NNHR. Mono- or bis-pyrazoles are similarly obtained from bis-diketones of the formula ##STR2##
公式为 ##STR1## 的4-(芳氧基烷基)
吡唑可作为抗病毒药物,通过将公式为 Ar--O--Alk--CH(COR')COR" 的相应二酮与
肼或取代
肼 H.sub.2 NNHR 反应制备。类似地,从公式为 ##STR2## 的双酮中也可获得单个或双
吡唑。
