Gegenstand der Erfindung ist ein Verfahren zur Herstellung von 2-Oxo-1, 3-diazacycloalkanverbindun- gen der Formel
EMI1.1
worin Rt einen niederen aliphatischen Kohlenwasserstoffrest, einen gegebenenfalls substituierten Phenylrest oder insbesondere ein Wasserstoffatom, Z einen niederen unverzweigten Alkylenrest, der die beiden Stickstoffatome durch 3 bis 5, insbesondere durch 3 oder 4, Kohlenstoffatome trennt und der durch einen oder mehrere gegebenenfalls substituierte Kohlenwasserstoffreste substituiert sein kann, und R ein Wasserstoffatom oder einen Rest Ro bedeutet, worin Ro für einen gegebenenfalls durch funktionelle Gruppen substituierten aliphatischen Kohlenwasserstoffrest,
vor allem für einen unsubstituierten oder durch eine Hydroxylgruppe oder eine freie oder substituierte Aminogruppe substituierten niederen Alkylrest, für einen niederen Alkenylrest oder für einen araliphatischen Rest steht.
Als Kohlenwasserstoffreste sind insbesondere niedere Alkylreste, Phenylreste und Phenylniederalkylreste, wie Benzyl- oder Phenyläthylreste, zu nennen. Als Substituenten dieser Phenyl- oder Phenylniederalkylreste kommen vor allem niedere Alkylreste, niedere Alkoxygruppen, wie Methoxy-, Athoxy-, Propoxy- oder Butoxygruppen, Halogenatome, wie Chlor oder Brom, Trifluoromethylgruppen oder Nitrogruppen in Betracht.
Niedere Alkylreste sind oben und nachfolgend vorzugsweise solche mit höchstens 5 Kohlenstoffatomen, wie Methyl-, Äthyl-, Propyl-, Isopropyl-, Butyl-, Isobutyl- oder Pentylreste. Niedere Alkenylreste sind vor allem Allyl- oder Methallylreste. Als araliphatische Reste seien vor allem Phenylniederalkylreste, wie Benzyl-, 1 -Phenyläthyl- Oder 2-Phenyläthylreste, erwähnt.
Substituierte Aminogruppen sind monosubstituierte, in erster Linie aber disubstituierte Aminogruppen, wobei als Substituenten vor allem Alkyl-, Alkenyl-, Alkylen-, Cycloalkyl-, Oxa- oder Aza-alkylenreste in Betracht kommen. Zu nennen sind z. B. Diniederalkyl-aminogruppen, wie Dimethyiamino-, Diäthylamino- oder Dipropylaminograppen, Pyrrolidino-, Piperidino-, Morpholino-, Hexa- oder Heptamethylenamino-, Piperazino-, N-Methyl-piperazino-oder N Hydroxyäthyl-piperazino-Gruppen.
Der substituierte Alkylrest ist besonders ein Hydroxy- oder tert. -Amino-methyl-, -äthyl- oder -pro- pylrest.
Die araliphatischen Reste können an den Kohlenstoffatomen substituiert sein, vor allem an den Arylresten durch Halogenatome, wie Chlor oder Brom, das Pseudohalogen Trifluormethyl, niedere Alkylgruppen, wie Methyl oder Äthyl, niedere Alkoxygruppen, wie Methoxy, Äthoxy oder Methylendioxy, oder auch Nitrogruppen.
Als niedere aliphatische Kohlenwasserstoffreste R1 kommen vor allem niedere Alkylreste in Frage, wie Methyl-, 2ithyl-, Propyl-, Isopropyl-, Butyl-, Isobutyloder Pentylreste, ferner auch niedere Alkenylreste, wie Allyl-oder Methallylreste. Als Substituenten von Phenylresten R1 kommen z. B. die oben angegebenen in Betracht.
Der Rest Z ist insbesondere ein Propylen-(1, 3)-, Butylen-(1,4)- oder Pentylen-(1,5)-Rest, der wie angegeben substituiert sein kann, vor allem durch niedere Alkylreste.
Die neuen Verbindungen besitzen wertvolle pharmakologische, insbesondere antiparasitäre und antibakterielle Eigenschaften. Sie zeigen vor allem eine Wirkung gegen Protozoen und Würmer und sind, z. B. am infizierten Tier, beispielsweise an Mäusen, gegen gram negative Bakterien, z. B. Salmonella typhi oder Coli Bazillen, wie Esch. coli, wirksam. Insbesondere wirken die neuen Verbindungen, wie sich z. B. bei Versuchen an Hamstern zeigt, gegen Trichomonaden und Amöben sowie, z. B. an Mäusen und Schafen, gegen Schistosomen. Ferner besitzen sie eine Wirkung gegen Coccidien. Die neuen Verbindungen sind entsprechend als antiparasitäre und antibakterielle Mittel nützlich. Insbesondere eignen sie sich zur Behandlung der durch die genannten Erreger verursachten Erkrankungen.
Die neuen Verbindungen sind aber auch wertvolle Zwischenprodukte für die Herstellung anderer nützlicher Stoffe.
Besonders hervorzuheben sind die Verbindungen der Formel
EMI2.1
worin R1 einen niederen Alkylrest oder insbesondere ein Wasserstoffatom, R2 einen niederen Hydroxyalkylrest, einen niederen tert. Aminoalkylrest, wie einen Di-niederaLkyl-aminoniederaIkylrest, einen Piperidino-, Pyrrolidine oder Morpholinoniederalkylrest, einen niederen Alkylrest, einen gegebenenfalls, z. B. wie oben angegeben, substituierten Phenylniederalkyfrest oder insbesondere ein Wasserstoffatom bedeutet und Z1 einen durch niedere Alkylreste substituierten oder insbesondere unsubstituierten Propylen-(1,3)-, Buty len-(1,4)- oder Pentylen-(1,5)-Rest darstellt.
Besonders wertvoll bezüglich ihrer biologischen Eigenschaften sind das l.-[5-Nitrothiazolyl-(2)1-2-oxo- hexahydropyrimidin, das l-[5-Nitrothiazolyl-(2)]-2-oxo- 3-(hydroxymethyl)-hexahydropyrimidin sowie das 1-[5 Nitrothiazolyl-(2)1-2-oxoil 3-diazacycloheptan.
Das erfindungsgemässe Verfahren zur Herstellung der neuen Verbindungen ist dadurch gekennzeichnet, dass man eine Verbindung der Formel
EMI2.2
worin R und R1 die angegebenen Bedeutungen haben, Z einen niederen unverzweigten Alkylenrest, der X vom Stickstoffatom durch 3 bis 5 Kohlenstoffatome trennt und der durch einen oder mehrere gegebenenfalls substituierte Kohlenwasserstoffreste substituiert sein kann, und X eine reaktionsfähig veresterte Hydroxylgruppe bedeutet, unter Abspaltung von Säure intramolekular kondensiert.
Eine reaktionsfähig veresterte Hydroxylgruppe ist dabei vorzugsweise eine solche, die mit starken anorganischen Säuren oder organischen Sulfonsäuren verestert ist, vor allem mit Halogenwasserstoffsäuren, wie Chlor-, Brom-oder Jodwasserstoffsäure oder Arylsulfonsäuren, wie Toluolsulfonsäuren.
Die intramolekulare Kondensation (Ringschluss) kann vorzugsweise durch Erhitzen, zweckmässig in Gegenwart polarer Lösungsmittel, vor allem Wasser, und/oder in Gegenwart von Kondensationsmitteln, besonders basischen Kondensationsmitteln, wie Alkaliacetaten oder ALkalicarbonaten, gegebenenfalls in einem geeigneten Lösungsmittel, wie einem Säureamid, z. B.
Dimethylformamid, vorgenommen werden.
In erhaltenen Verbindungen kann man im Rahmen der Endstoffe weitere Substituenten einführen oder vorhandene Substituenten abspalten oder umwandeln.
So kann man insbesondere in erhaltenen Verbindungen, in denen R ein Wasserstoffatom bedeutet, einen der eingangs angegebenen Substituenten R einführen.
Dies geschieht in an sich bekannter Weise, z. B. zur Herstellung von Verbindungen, in denen der Substituent R keine Heteroatome aufweist oder in denen gegebenenfalls in R vorhandene Heteroatome durch mindestens 2 Kohlenstoffatome vom Ringstickstoffatom getrennt sind, durch Reaktion mit reaktionsfähigen Estern von Alkoholen der Formel R-OH. Reaktionsfähige Ester sind dabei solche mit starken anorganischen Säuren oder organischen Sulfonsäuren, vor allem mit Halogenwasserstoffsäuren, z. B. Chlor-, Brom- oder Jodwasserstoffsäure, oder Schwefelsäure, oder Aryloder Alkansulfonsäuren, vor allem Phenyl-, wie Toluolsulfonsäuren.
Dabei arbeitet man, wenn erwünscht, mit einem Metall-, wie Alkalimetallsalz, der in 3-Stellung unsubstituierten 2-Oxo-1, 3-diazacycloaLkan- verbindung, oder in Gegenwart eines basischen Kondensationsmittels, besonders eines Metallsalze bildenden Kondensationsmittels, wie Amiden, Hydriden, Kohlenwasserstoffverbindungen, Hydroxyden, Alkoholaten oder Carbonaten von Alkalimetallen.
Verbindungen, in denen der Rest R ein eine Hydro xylgruppe oder eine freie oder substituierte Aminogruppe tragender Methylrest, besonders ein Hydroxy methyl- oder sek.- oder tert.-Aminomethylrest ist, werden durch Reaktion mit t Formaldehyd gegebenen- falls in Gegenwart von Ammoniak oder Aminen erhalten.
Die Einführung der Hydroxymethylgruppe geschieht durch einfache Reaktion mit Formaldehyd, gegebenenfalls in Form eines Formaldehyd-Donators, wie Trioxymethylen oder Paraformaldehyd, vorteilhaft in Gegenwart eines basischen Kondensationsmittels, wie eines Alkalihydroxyds oder -carbonats oder tertiärer Amine oder quaternärer Ammoniumhydroxyde, wie Triäthylamin oder B enzyltrimethylammoniumhydroxyd.
Die Einführung der Aminomethylgruppe erfolgt zweckmässig gemäss der Mannich-Reaktion, z. B. mit Formaldehyd unter Verwendung eines Salzes des Ammoniaks oder Amins. Der Formaldehyd kann auch hier in Form eines Donators, wie Trioxymethylen oder Paraformaldehyd, gegebenenfalls in Gegenwart einer Säure, verwendet werden.
Die genannten Reaktionen können in üblicher Weise, in An- oder Abwesenheit von Verdünnungsmitteln, Kondensationsmitteln und/oder Katalysatoren, bei erniedrigter, gewöhnlicher oder erhöhter Temperatur, bei normalem oder erhöhtem Druck und/oder unter einer Inertgasatmosphäre durchgeführt werden.
Je nach den Verfahrensbedingungen und Ausgangsstoffen erhält man Aminogruppen enthaltende Endstoffe in freier Form oder in der ebenfalls in der Erfindung inbegriffenen Form ihrer Salze. Erhaltene Amine lassen sich in üblicher Weise durch Umsetzung mit organischen oder anorganischen Säuren, insbesondere solchen, die zur Bildung therapeutisch verwendbarer Salze geeignet sind, in Salze umwandeln. Anderseits lassen sich die erhaltenen Salze in üblicher Weise, z. B. durch Behandlung mit basischen Mitteln oder Ionen austauschern, in die freien Verbindungen überführen.
Als Säuren, die für die Bildung therapeutisch verwendbarer Salze geeignet sind, seien beispielsweise genannt: Halogenwasserstoffsäuren, Schwefelsäuren, Phosphorsäuren, Salpetersäure; Perchlorsäure, alicyclische, aromatische oder heterocyclische Carbon- oder Sulfonsäuren, wie Ameisen-, Essig-, Propion-, Bernstein-, Glykol-, Milch-, Sipfel-, Wein-, Zitronen-, Ascorbin-, Malein-, Hydroxymalein- oder Brenztraubensäure; Phenylessig-, Benzoe-, p-Amino-benzoe-, Anthranil-, p-Hydroxy-benzoe-, Salicyl-, p-Aminosalicyl- oder Embonsäure, Methansulfon¯, Sithansulfon-, Hydroxy äthansulfon-, Äthylensulfonsäure; Halogenbenzolsulfon-, Toluolsulfon-, Naphthalinsulfonsäuren oder Sulfanilsäure; Methionin, Tryptophan, Lysin oder Arginin.
Diese oder andere Salze der neuen Verbindungen, wie z. B. die Pikrate, können auch zur Reinigung der erhaltenen Basen dienen, indem man diese in Salz überführt, die Salze abtrennt und aus den Salzen die Basen freisetzt. Infolge der engen Beziehungen zwischen den Verbindungen in freier Form und in Form ihrer Salze sind im vorausgegangenen und nachfolgend unter den freien Verbindungen sinn- und zweckgemäss gegebenenfalls auch die entsprechenden Salze zu verstehen.
Die Ausgangsstoffe können auch in situ hergestellt werden. So kann man auch von entsprechenden N-f [5-Nitrothiazolyl-(2)]-N'-co-hydroxy-propyl-, butyl oder-pentyl-Harnstoffen ausgehen und diese in saurem Milieu, z. B. in konzentrierter Schwefelsäure, zu den gewünschten 2-Oxo-1, ,3-diazacycloalkanverbindungen ringschliessen. Dabei entstehen intermediär durch Säureanlagerung bzw. Veresterung die Ester, die verfahrensgemäss den gewünschten Ring bilden.
Zweckmässig verwendet man solche Ausgangsstoffe, die zu den eingangs als besonders wertvoll geschilderten Endstoffen führen.
Die verwendeten Ausgangsstoffe sind bekannt oder werden, falls neu, in an sich bekannter Weise hergestellt.
Die neuen Verbindungen können als Heilmittel, z. B. in Form pharmazeutischer Präparate, Verwendung finden, welche sie oder ihre Salze in Mischung mit einem für die enterale, parenterale oder topicale Applikation geeigneten pharmazeutischen organischen oder anorganischen, festen oder flüssigen Trägermaterial enthalten.
Die eingangs genannten Verbindungen können aber auch in Form von Futter- bzw. Futterzusatzmitteln bei der Aufzucht von Tieren Verwendung finden.
In den nachfolgenden Beispielen sind die Temperaturen in Celsiusgraden angegeben.

Den unlöslichen Anteil filtriert man ab und kristallisiert aus Dimethylformamid um. Man erhält so das 1-[5-Nitro-thiazolyl-(2)]-2-oxo- hexahydro-pyrimidin der Formel
EMI3.1
in Kristallen von F. 289".
Den als Ausgangsmaterial verwendeten Harnstoff kann man wie folgt erhalten:
14,4 g 2-Amino-5-nitrbthiazol und 13,0 g 3-Chlorpropylisocyanat werden in 100 mol Dioxan während 5 Stunden auf 1000 erwärmt. Der unlösliche Anteil wird hierauf filtriert. Das Filtrat dampft man ein und kristallisiert den Rückstand aus Dioxan-Wasser um. Der N - [5 -Nitro - thiazolyl - (2)]-N'-(3-chlorpropyl)-Harnstoff wird in Kristallen von F. 168-1700 erhalten.

Der Niederschlag wird abgenutscht und aus 2-n-Salzsäure umkristallisiert. Das 1 - [5-Nitro-thiazolyl-(2)] -2-oxo-3-(dimethyl- aminomethyl)-hexahydro-pyrimidin-hydrochlorid der Formel

Die neuen Verbindungen, insbesondere das 1-[5 Nitrothiazolyl-(2)]-oxosshexahydropyrimidin, können als Zusatz zu Tierfutter, z. B. Geflügelfutter, verwendet werden. So kann z.

Diese Vormischung kann dann dem Futter in üblicher Weise zugesetzt werden, zweckmässig so, dass der Gehalt an Pyrimidinderivat ca.
0,01 O/o beträgt.

To be mentioned are z. B. di-lower alkyl amino groups, such as dimethylamino, diethylamino or dipropylamino groups, pyrrolidino, piperidino, morpholino, hexa- or heptamethyleneamino, piperazino, N-methyl-piperazino or N-hydroxyethyl-piperazino groups.
The substituted alkyl radical is especially a hydroxy or tert. -Amino-methyl-, -ethyl- or -propyl radical.

B. in experiments on hamsters shows against trichomonads and amoebas and, for. B. on mice and sheep, against schistosomes. They also have an effect against coccidia. The new compounds are accordingly useful as antiparasitic and antibacterial agents. In particular, they are suitable for treating the diseases caused by the pathogens mentioned.
The new compounds are also valuable intermediates for the production of other useful substances.
Particularly noteworthy are the compounds of the formula
EMI2.1
wherein R1 is a lower alkyl radical or, in particular, a hydrogen atom, R2 is a lower hydroxyalkyl radical, a lower tert.

The process according to the invention for preparing the new compounds is characterized in that a compound of the formula
EMI2.2
where R and R1 have the meanings given, Z is a lower unbranched alkylene radical which separates X from the nitrogen atom by 3 to 5 carbon atoms and which can be substituted by one or more optionally substituted hydrocarbon radicals, and X is a reactive esterified hydroxyl group, with elimination of acid intramolecularly condensed.
A reactive esterified hydroxyl group is preferably one which has been esterified with strong inorganic acids or organic sulfonic acids, especially with hydrohalic acids such as hydrochloric, bromic or hydroiodic acid or arylsulfonic acids such as toluenesulfonic acids.
The intramolecular condensation (ring closure) can preferably be carried out by heating, suitably in the presence of polar solvents, especially water, and / or in the presence of condensing agents, particularly basic condensing agents such as alkali metal acetates or alkali metal carbonates, optionally in a suitable solvent such as an acid amide, e.g. B.
Dimethylformamide.
In the compounds obtained, further substituents can be introduced within the scope of the end products or existing substituents can be split off or converted.
For example, in compounds obtained in which R is a hydrogen atom, one of the substituents R given at the outset can be introduced.
This is done in a manner known per se, e.g. B. for the preparation of compounds in which the substituent R has no heteroatoms or in which any heteroatoms present in R are separated from the ring nitrogen atom by at least 2 carbon atoms, by reaction with reactive esters of alcohols of the formula R-OH. Reactive esters are those with strong inorganic acids or organic sulfonic acids, especially with hydrohalic acids, e.g. B. chlorine, bromine or hydroiodic acid, or sulfuric acid, or aryl or alkanesulfonic acids, especially phenyl, such as toluenesulfonic acids.

Compounds in which the radical R is a methyl radical bearing a hydroxyl group or a free or substituted amino group, especially a hydroxymethyl or sec- or tert-aminomethyl radical, are produced by reaction with formaldehyde, optionally in the presence of ammonia or Amines obtained.
The hydroxymethyl group is introduced by a simple reaction with formaldehyde, optionally in the form of a formaldehyde donor such as trioxymethylene or paraformaldehyde, advantageously in the presence of a basic condensing agent such as an alkali hydroxide or carbonate or tertiary amines or quaternary ammonium hydroxides such as triethylamine or benzyltrimethylammonium.
The aminomethyl group is conveniently introduced according to the Mannich reaction, e.g. B. with formaldehyde using a salt of ammonia or amine. The formaldehyde can also be used here in the form of a donor, such as trioxymethylene or paraformaldehyde, optionally in the presence of an acid.
The reactions mentioned can be carried out in the customary manner, in the presence or absence of diluents, condensing agents and / or catalysts, at reduced, ordinary or elevated temperature, at normal or elevated pressure and / or under an inert gas atmosphere.
Depending on the process conditions and starting materials, end products containing amino groups are obtained in free form or in the form of their salts, which is also included in the invention. Amines obtained can be converted into salts in the usual way by reaction with organic or inorganic acids, in particular those which are suitable for the formation of therapeutically useful salts. On the other hand, the salts obtained can be in the usual way, for. B. exchange by treatment with basic agents or ions, converted into the free compounds.
Examples of acids which are suitable for the formation of therapeutically useful salts are: hydrohalic acids, sulfuric acids, phosphoric acids, nitric acid; Perchloric acid, alicyclic, aromatic or heterocyclic carboxylic or sulfonic acids, such as formic, acetic, propionic, succinic, glycolic, lactic, sipfelic, tartaric, lemon, ascorbic, maleic, hydroxymaleic or pyruvic acid ; Phenylacetic, benzoic, p-amino-benzoic, anthranil, p-hydroxy-benzoic, salicylic, p-aminosalicylic or emboxylic acid, methanesulphonic, sithanesulphonic, hydroxyethanesulphonic, ethylene sulphonic acid; Halobenzenesulfonic, toluenesulfonic, naphthalenesulfonic acids or sulfanilic acid; Methionine, tryptophan, lysine or arginine.
These or other salts of the new compounds, such as. B. the picrates can also be used to purify the bases obtained by converting them to salt, separating the salts and releasing the bases from the salts. As a result of the close relationships between the compounds in free form and in the form of their salts, in the preceding and in the following the free compounds are to be understood, appropriately and appropriately, also to mean the corresponding salts.
The starting materials can also be produced in situ. So you can start from the corresponding N-f [5-nitrothiazolyl- (2)] - N'-co-hydroxypropyl, butyl or pentyl ureas and these in an acidic medium, eg. B. in concentrated sulfuric acid, to form the desired 2-oxo-1,, 3-diazacycloalkane compounds. The esters are formed as an intermediate through acid addition or esterification, which according to the process form the desired ring.
It is expedient to use those starting materials which lead to the end materials described at the beginning as being particularly valuable.
The starting materials used are known or, if new, are produced in a manner known per se.
The new compounds can be used as remedies, e.g. B. in the form of pharmaceutical preparations, which contain them or their salts in a mixture with a pharmaceutical organic or inorganic, solid or liquid carrier material suitable for enteral, parenteral or topical application.
The compounds mentioned at the outset can also be used in the form of feed or feed additives when raising animals.
In the following examples, the temperatures are given in degrees Celsius.

The insoluble fraction is filtered off and recrystallized from dimethylformamide. This gives 1- [5-nitro-thiazolyl- (2)] - 2-oxo-hexahydropyrimidine of the formula
EMI3.1
in crystals of F. 289 ".
The urea used as the starting material can be obtained as follows:
14.4 g of 2-amino-5-nitrobthiazole and 13.0 g of 3-chloropropyl isocyanate are heated to 1000 in 100 mol of dioxane for 5 hours. The insoluble portion is then filtered. The filtrate is evaporated and the residue is recrystallized from dioxane-water. The N - [5 -nitro - thiazolyl - (2)] - N '- (3-chloropropyl) urea is obtained in crystals of F. 168-1700.
Example 2
To a warm solution of 7.0 g of 1- [5-nitrothiazolyl- (2)] - 2-oxo-hexahydropyrimidine in 30 ml of dimethylformamide are added 2 drops of a 500% solution of benzyltrimethylammonium hydroxide in ethanol and 50 ml of formalin (400 / oig ). After one hour, 200 ml of water are added and the mixture is recrystallized from methanol. The 1- [5-nitrothiazolyl- (2)] - 3-hydroxymethyl-2-oxo-hexahydropyrimidine of the formula is obtained
EMI3.2
in crystals from F. 158-160.
Example 3
2.5 g of 1 - [5-nitro-thiazoyl- (2)] - 2-oxo-hexahydropyrimidine, 0.33 g of paraformaldehyde and 0.9 g of dimethylamine hydrochloride are heated in 25 cm of dimethylformamide for 2 hours at 100 " The precipitate is filtered off with suction and recrystallized from 2N hydrochloric acid, the 1 - [5-nitro-thiazolyl- (2)] -2-oxo-3- (dimethylaminomethyl) hexahydropyrimidine hydrochloride of the formula
EMI3.3
melts with addition at 2580.
Example 4
The new compounds, especially 1- [5 nitrothiazolyl- (2)] - oxosshexahydropyrimidine, can be used as an additive to animal feed, e.g. B. poultry feed can be used. So z. B. 1- [5-nitrothiazolyl (2)] - 2 <xo-hexahydropyrimidine can be mixed with cerelose (content of active compound, for example 0.1-1%, preferably 0.5 / o). This premix can then be added to the feed in the usual way, expediently so that the pyrimidine derivative content is approx.
Is 0.01 o / o.
