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)
吡唑是一种有用的抗病毒药物,通过将公式为Ar-O-Alk-CH(COR')COR"的相应二酮与
肼或取代
肼H2NNHR反应制备。类似地,从公式为##STR2##的双二酮中也可以获得单个或双
吡唑。
