Fra J. Org. Chem. 34, Nr. 4, 1969, s. 1143-1145 er det kendt at amidere cycliske amider i nærværelse af complexer af titan (IV) med ammoniak, primære eller sekundære aminer. Ved denne metode fører nærværelse af titantetrachlorid hovedsagelig til en spaltning af lactambindingen, hvorved der indtræder omamidering, hvorfor der kun fås ringe udbytter af ami-diner. Det har nu vist sig, at cycliske amider kan amideres ved hjælp af titan IV- eller zirconium-IV-piperazincomplexer med godt udbytte.From J. Org. Chem. 34, no. 4, 1969, pp. 1143-1145, it is known to amide cyclic amides in the presence of complexes of titanium (IV) with ammonia, primary or secondary amines. In this method, the presence of titanium tetrachloride mainly leads to a cleavage of the lactam bond, which results in re-amidation, so that only poor yields of amine dinar are obtained. It has now been found that cyclic amides can be amidated by titanium IV or zirconium IV piperazine complexes in good yield.

En foretrukken udførelsesform af fremgangsmåden ifølge opfindelsen består i, at forbindelser med formlen II omsættes med metal-amin-complexet i nærværelse af et syrebindende middel. Som syrebindende middel kan anvendes en tertiær amin, f.eks. triethylamin, pyridin, dimethylanilin eller et overskud af en forbindelse med formlen III. Andelen af den syrebindende aminoforbindelse beregnet på (1 mol) metal-amin-complex skal være mindst 1 mol (ækvivalent mængde), dog fortrinsvis 2 mol (dobbelt ækvivalent mængde).A preferred embodiment of the process of the invention consists in reacting compounds of formula II with the metal-amine complex in the presence of an acid-binding agent. As an acid binding agent a tertiary amine, e.g. triethylamine, pyridine, dimethylaniline or an excess of a compound of formula III. The proportion of the acid-binding amino compound calculated on (1 mole) metal-amine complex must be at least 1 mole (equivalent amount), but preferably 2 mole (double equivalent amount).
Omsætningen udføres hensigtsmæssigt i et organisk opløsningsmiddel, f.eks. et aromatisk opløsningsmiddel såsom toluen, et halogeneret aromatisk opløsningsmiddel såsom chlorbenzen, et halogeneret aliphatisk opløsningsmiddel såsom dichlorethan eller en ether såsom anisol. Reaktionstemperaturen skal her ligge mellem stuetemperatur og 150°C, fortrinsvis mellem 50 og 120°C.The reaction is conveniently carried out in an organic solvent, e.g. an aromatic solvent such as toluene, a halogenated aromatic solvent such as chlorobenzene, a halogenated aliphatic solvent such as dichloroethane or an ether such as anisole. Here, the reaction temperature should be between room temperature and 150 ° C, preferably between 50 and 120 ° C.
2 3 4 I substituenterne R , R og R er halogen fortrinsvis chlor eller brom, især chlor. Såfremt hydroxyalkylgruppen R er acyleret, indeholder acylgruppen højst 18 carbonatomer, fortrinsvis højst 10 carbonatomer. Acylgruppen er fortrinsvis aliphatisk og kan være mættet eller umættet.In the substituents R, R and R, halogen is preferably chlorine or bromine, especially chlorine. If the hydroxyalkyl group R is acylated, the acyl group contains at most 18 carbon atoms, preferably at most 10 carbon atoms. The acyl group is preferably aliphatic and may be saturated or unsaturated.
Det til den omhandlede omsætning anvendte metal-amin-complex fås ved omsætning af et halogenid, fortrinsvis tetrachloridet eller tetrabromidet af titan eller zirconium med en forbindelse med formlen III, hensigtsmæssigt i et molforhold på 1:4. Omsætningen foretages hensigtsmæssigt i det senere til hoved reaktionen anvendte opløsningsmiddel. Hertil anvendes metalhalogenidet i form af dets opløselige (mono- eller di-) etherat, fortrinsvis anisol-dietheratet.The metal-amine complex used for the present reaction is obtained by reacting a halide, preferably the tetrachloride or tetrabromide of titanium or zirconium with a compound of formula III, suitably in a molar ratio of 1: 4. The reaction is conveniently carried out in the solvent used for the main reaction. To this end, the metal halide is used in the form of its soluble (mono or di) etherate, preferably the anisole dietherate.

Efter endt omsætning omdannes de i reaktionsblandingen værende, i vid udstrækning uopløselige metalforbindelser ved tilsætning af en alkohol,f.eks. isopropanol, til en opløselig form og udfæl= des derefter ved tilsætning af vandig ammoniak. Af den således for metalforbindelser befriede reaktionsblanding isoleres de ifølge opfindelsen fremstillede forbindelser med formlen I på i og for sig kendt måde efter inddampning af reaktionsblandingen ved ud= krystallisation og renses derefter på i og for sig kendt måde, f.eks. ved omkrystallisation af isopropanol.Upon completion of the reaction, the largely insoluble metal compounds in the reaction mixture are converted by the addition of an alcohol, e.g. isopropanol, to a soluble form and then precipitated by the addition of aqueous ammonia. From the reaction mixture thus liberated for metal compounds, the compounds of the formula I according to the invention are isolated in a manner known per se after evaporation of the reaction mixture by crystallization and then purified in a manner known per se, e.g. by recrystallization from isopropanol.
Ted fremstillingen af forbindelserne med formlen I, hvor R1 er en hydroxy-alkylgruppe, kan reaktionsproduktet udfældes geléagtigt, da hydroxyalkylgruppen ligeledes reagerer med metalhalogenidet under esterdannelse. For at forhindre dannelsen af en for stærk gelé, som kan forstyrre reaktionsforløbet, er det hensigtsmæssigt at arbejde i nærværelse af større mængder opløsningsmidler, f.eks. chlorbenzen eller anisol, under- tilsætning af et overskud (10 -20 ganges molært overskud) af en tertiær amin, f.eks. triethylamin.For the preparation of the compounds of formula I wherein R 1 is a hydroxyalkyl group, the reaction product can be precipitated gelled as the hydroxyalkyl group also reacts with the metal halide during ester formation. In order to prevent the formation of an overly strong jelly which may interfere with the course of the reaction, it is advisable to work in the presence of larger quantities of solvents, e.g. chlorobenzene or anisole, adding an excess (10-20 times the molar excess) of a tertiary amine, e.g. triethylamine.
Forbindelser med formlen I, hvor R er en hydroxyalkylgruppe, kan ligeledes fremstilles ved alkalisk hydrolyse af forbindelser med formlen I, hvor R1 er en acyleret hydroxyalkylgruppe, f.eks. ved hjælp af en fortyndet natriumhydroxidopløsning.Compounds of formula I wherein R is a hydroxyalkyl group may also be prepared by alkaline hydrolysis of compounds of formula I wherein R 1 is an acylated hydroxyalkyl group, e.g. using a dilute sodium hydroxide solution.
Forestringen af forbindelser med formlen I, hvor R1 er en hydroxy= alkylgruppe, kan foretages på i og for sig kendt måde, f.eks. ved hjælp af et reaktivt syrederivat, f.eks. et halogenid af en relevant syre, i et opløsningsmiddel såsom chloroform, hensigtsmæssigt i nærværelse af et syrebindende middel, f.eks. triethylamin, ved stuetemperatur.The esterification of compounds of formula I wherein R 1 is a hydroxy = alkyl group may be carried out in a manner known per se, e.g. by means of a reactive acid derivative, e.g. a halide of a relevant acid, in a solvent such as chloroform, conveniently in the presence of an acid binding agent, e.g. triethylamine, at room temperature.
De resulterende forbindelser med formlen I kan omdannes til syre= additionssalte deraf og omvendt. Egnede salte er f.eks. hydro= chlorider, hydrobromidet, sulfater, fumarater, maleinater og p-toluensulfonater.The resulting compounds of formula I can be converted into acid addition salts thereof and vice versa. Suitable salts are e.g. hydro = chlorides, the hydrobromide, sulfates, fumarates, maleinates and p-toluenesulfonates.

Forbindelserne med formlen III er i almindelighed også kendte eller kan fremstilles ud fra kendte udgangsforbindelser på i og for sig kendt måde. Forbindelser med formlen III, hvor R^” er en aeyleret hydroxyalkylgruppe, kan f.eks. fremstilles ved omsætning af E-benzylpiperazin med en halogenal= kohol, hydroxygruppen kan forestres ved hjælp af et reaktivt syre= derivat, f.eks. halogenidet, især chloridet, af en relevant syre, hvorefter benzylgruppen fjernes hydrogenolytisk.The starting compounds of formula I used for the process according to the present invention are for the most part known or can be prepared from known starting compounds in a manner known per se. The preparation of compounds of formula II as yet unknown is described in the Examples or may be analogous to these Examples. The compounds of formula III are generally also known or can be prepared from known starting compounds in a manner known per se. Compounds of formula III wherein R 2 is an aeylated hydroxyalkyl group can be, for example, is prepared by reaction of E-benzylpiperazine with a haloalcohol, the hydroxy group can be esterified by a reactive acid = derivative, e.g. the halide, especially the chloride, of a relevant acid, after which the benzyl group is removed hydrogenolytically.
