Description
Verfahren zur Herstellung von Hydrazinverbindungen
Als Hydrazine verwendet man das Hydrazin selbst oder seine Substitutionsprodukte, wobei ein Stickstoffatom auch einen Teil eines Ringes, z. B. des Piperidin- oder Morpholinringes, bilden kann. Erwähnt werden folgende Hydrazine: Hydrazin, Methylhydrazin, asymm. Dimethylhydrazin, symm. Dimethylhydrazin, Propylhydrazin, Allylhydrazin, - Nlethyl - N - liutylhydrazin, N - Aminopiperidin, N - Aminomorpholin, 3 - Methylcycloliexylhydrazin u. dgl. Diese Hydrazine können auch in Form ihrer Salze zur Anwendung kommen. Die Umsetzung mit den Hydrazinen wird zweckmäßig in Anwesenheit von Verdünnungsmitteln, allenfalls auch in Gegenwart von Kondensationsmitteln durchgeführt, wobei man außerdem in Gegenwart von Katalysatoren, mie Kupferpulver, arbeiten kann.The hydrazine itself or its substitution products are used as hydrazines, wherein a nitrogen atom also forms part of a ring, e.g. B. the piperidine or Morpholine ring. The following hydrazines are mentioned: hydrazine, methylhydrazine, asymm. Dimethylhydrazine, symm. Dimethylhydrazine, propylhydrazine, allylhydrazine, - Nlethyl - N - liutylhydrazine, N - aminopiperidine, N - aminomorpholine, 3 - methylcycloliexylhydrazine and the like. These hydrazines can also be used in the form of their salts. the Reaction with the hydrazines is expedient in the presence of diluents, at most also carried out in the presence of condensing agents, with one also can work in the presence of catalysts, such as copper powder.
Die verfahrensgemäße Reduktion z. B. der Nitroaminoverbindungen zu Hydrazinen kann beispielsweise katalytisch oder mit Zinkstaub in Gegenwart von Natronlauge durchgeführt werden.The procedural reduction z. B. the nitroamino compounds Hydrazines can, for example, catalytically or with zinc dust in the presence of caustic soda be performed.
Soweit die genannten Ausgangsstoffe nicht bekannt sind, können sie nach den üblichen Methoden gewonnen «erden.If the starting materials mentioned are not known, they can obtained by the usual methods.
Die erhaltenen Hydrazine bilden leicht Salze. Enthalten sie freie Aminogruppen, so lassen sie sich mit Carbonylverbindungen, wie Aldehyden und Ketonen, kondensieren. Auch mit acylierenden -Mitteln, wie Ameisensäure, Chloridcn und Anhydriden organischer Säuren, beispielsweise AcetylchIorid, Essigsäureanhydrid, Benzoylchlorid, treten sie leicht in Reaktion.The hydrazines obtained easily form salts. Do they contain free Amino groups, they can be combined with carbonyl compounds such as aldehydes and ketones, condense. Also with acylating agents such as formic acid, chlorides and anhydrides organic acids, for example acetyl chloride, acetic anhydride, benzoyl chloride, react easily.
Nach dem vorliegenden Verfahren gewonnene Verbindungen besitzen wertvolle pharmakologische Eigenschaften. So bewirkt z. B. das 1, 4-Dihydrazinophthalazin eine besonders lang andauernde Blutdrucksenkung. Sie sollen als Heilmittel oder als Zwischenprodukte Verwendung finden.Compounds obtained by the present process have valuable compounds pharmacological properties. So z. B. 1,4-Dihydrazinophthalazine a particularly long-lasting decrease in blood pressure. They are supposed to be used as a remedy or find use as intermediates.
Die Erfindung wird in den folgenden Beispielen näher beschrieben, wobei zwischen Gewichtsteil und Volumteil die gleiche Beziehung besteht wie z«-ischen Gramm und Kubikzentimeter. Die Temperaturen werden in Celsiusgraden angegeben. Beispiel 6,6 Gewichtsteile i - Chlor - 4 - methoxyphthalazin (F. i o8 bis i o9`, erhalten aus 1, 4-Dichlorplitiialazin und Natriummethylat )werden zu einem warmen Gemisch von 25 Volumteilen Hydrazinhydrat und 25 Voltimteileii absolutem Äthylalkohol gegeben. Es tritt sofort Auflösung ein. Nach zweistündigem Erwä rmeii auf dem Wasserbade wird abgekühlt, wobei die Kristallisation einsetzt. Durch Absaugen und Waschen mit Äthylalkohol «-erden etwa 5 Gewichtsteile einer orange gefärbten Verbindung erhalten, welche aus Wasser in feinen Nädelchen kristallisiert und bei etwa i 8o' schmilzt. Die Analysenwerte stimmen auf i , 4 - Dihydrazinophthalazin von der Formel Das Dihydrochlorid läßt sich mit 2n-Salzsäure gewinnen. Es kristallisiert mit etwas Kristallwasser und schmilzt unscharf unter Zersetzung bei etwa z55°.The invention is described in more detail in the following examples, the relationship between part by weight and part by volume being the same as that of grams and cubic centimeters. The temperatures are given in degrees Celsius. Example 6.6 parts by weight of i - chloro - 4 - methoxyphthalazine (F. i o8 to i o9 ', obtained from 1,4-dichloroplitiialazine and sodium methylate) are added to a warm mixture of 25 parts by volume of hydrazine hydrate and 25 parts by volume of absolute ethyl alcohol. Dissolution occurs immediately. After two hours of warming on the water bath, the mixture is cooled and crystallization begins. By suction and washing with ethyl alcohol "earths, about 5 parts by weight of an orange-colored compound are obtained, which crystallizes from water in fine needles and melts at about 18o". The analytical values agree with 1,4-dihydrazinophthalazine of the formula The dihydrochloride can be obtained with 2N hydrochloric acid. It crystallizes with some water of crystallization and melts indistinctly with decomposition at about z55 °.
An Stelle von i-Chlor-4-methoxyphthalazin kann man auch von der entsprechenden 4-Äthoxyverhiiidung ausgehen. Diese wird aus i, 4-Dichlorphthalazin in Äthylalkohol in Gegenwart von Natriumäthylat erhalten und schmilzt bei -K. Instead of i-chloro-4-methoxyphthalazine, one can also start from the corresponding 4-ethoxy avoidance. This is obtained from i, 4-dichlorophthalazine in ethyl alcohol in the presence of sodium ethylate and melts at -K.
Verwendet man als Ausgangspunkt 1, 4 - Diphenoxyphthalazin (F. 22o°, erhalten aus 1, 4 - Di-Chlorphthala7-in und Natiitimphenolat ), so wird die Umsetzung mit Hydrazinhydrat vorteilhaft bei erhöhter Temperatur im Bombenrohr durchgeführt.If one uses 1, 4 - diphenoxyphthalazine (F. 22o °, obtained from 1, 4 - di-chlorophthalene-yne and natiitimphenolat), the reaction is carried out with hydrazine hydrate advantageously at elevated temperature in a sealed tube.
Unter milden Bedingungen läßt sich durch Einwirkung von Hydrazinhydrat auf 1, 4-Dichlorplitlualazin das i-Hy#drazino-4-clilorplitlialazin gcivinncn (Hydrochlorid F. etwa 220 i, «-elches durch Einwirkung energiesicherer Bedingungen weiter in das 1, 4-Dihydrazinophthalaziit vom F. u So übergeführt werden kann.Under mild conditions, hydrazine hydrate can be used on 1,4-dichloroplitlualazine the i-Hy # drazino-4-clilorplitlialazin gcivinncn (hydrochloride F. about 220 i, "-which by the action of energy-safe conditions further into the 1, 4-Dihydrazinophthalaziit from F. u So can be transferred.
