New pyridazinium compounds which can be used as intermediates and are of interest because of their pharmacological properties, and their production. The invention relates to new pyridazinium compounds and their production. These compounds are of pharmacological interest. In DOS No. 1,912,941 6-alkoxypyridazinium compounds are said to have valuable pharmacological properties. Furthermore pyridazinium compounds are known for example as starting materials for pesticides and dyes from DOS No. 2,003,461 or U.S. Patent 3,510,488. The quaternization of pyridazines into pyridazinium compounds is described in an article in Acta. Chem. Scand., 21 (1967), 1067 to 1080, and the reaction of 6-chloropyridazinium compounds with amines is described in volume 23 (1969), 2534 to 2536.
新的吡啶啉化合物可用作中间体,并因其药理学性质和生产而受到关注。该发明涉及新的吡啶啉化合物及其生产。这些化合物具有药理学上的重要性。在DOS编号1,912,941中,6-烷氧基吡啶啉化合物被认为具有有价值的药理学性质。此外,吡啶啉化合物已被认为是杀虫剂和染料的起始原料,例如来自DOS编号2,003,461或美国专利3,510,488。吡啶啉化合物的季铵化反应在Acta. Chem. Scand.的文章中有描述,该文章发表于1967年第21卷,第1067至1080页,6-氯吡啶啉化合物与胺的反应在第23卷(1969年)2534至2536页有描述。
