The compounds are aryl-pyridazinone derivatives, e.g., 1-methyl-5-(2'-fluoro-5'-trifluoromethylphenyl)-1H-pyrazolo [4,3-c]pyridazin-6(5H)-one. They are useful as antihypertensives and are prepared by treating a hydrazinopyridazinone with a dialkylamino dialkyl-acetal.
这些化合物是芳基吡啶嗪衍生物,例如1-甲基-5-(2'-氟-5'-三氟甲基苯基)-1H-吡唑并[4,3-c]吡啶嗪-6(5H)-酮。它们可用作降压药,并通过将一种肼基吡啶嗪与二烷基氨基二烷基缩醛处理而制备。
