      Process for the preparation of new triazines The present invention relates to the preparation of 2- (2'-pyrid'oylhydrazino) -4,6-bis-diethylamino-1,3,5-triazines of the formula
EMI0001.0007
    wherein Py is a pyridyl radical. In these compounds, the pyridyl radical can be substituted, e.g. B.

    by lower alkyl radicals such as methyl, ethyl, propyl or butyl, halogen atoms such as chlorine or bromine, nitro or amino groups. However, it is preferably unsubstituted. He can carry the carbonyl group in any position, but especially in the 3- or 4-position.



  The new compounds and their salts have valuable pharmacological properties. So they have an inhibitory effect on the transmission of excitation in the central nervous system and can of half as a remedy, for. B. as a spinal blocker, in neurological diseases, especially those that are associated with increased Spastizitäb, who used the. It can also be used in veterinary medicine.



  The compounds of the formula are particularly valuable
EMI0001.0035
    and their salts, in which Py 'represents the pyridyl (3) or the pyridyl (4) radical.



  The process according to the invention consists in acylating 2-hydrazino-4,6-bis-diethylamino-1,3,5 = triazine with a compound which introduces the acyl radical of a pyridinecarboxylic acid. Compounds introducing the acyl radical of a pyridinecarboxylic acid are primarily pyridylcarboxylic acids,

      expediently in the form of their reactive functional acid derivatives, especially the esters, anhydrides or halides, optionally in the form of their salts. The reaction is advantageously carried out in the presence of a condensing agent such as an inorganic or organic base. Tertiary organic bases, such as pyridine or trialkylamines, e.g.

   B. trim methyl or triethylamine, metal salts of the used th carboxylic acids or anhydrous alkali metal carbonates, eg. B. Soda.



       It is advantageous to use the hydrazine compound with an acid addition salt, e.g. B. a hydrohalide such as hydrochloride, a pyridine-carboxylic acid halide @, z. B. a chloride, in the presence of one of the basic condensing agents mentioned, especially a strong organic tertiary base such as a trialkylamine.



  Depending on the procedure, the new compounds are obtained in the form of the free bases or their salts. Therapeutically usable salts can be formed from the bases, e.g.

   B. hydrohalic acids, sulfuric acids, phosphoric acids, nitric acid, perchloric acid; aliphatic, alicyclic, aromatic or heterocyclic carboxylic or sulfonic acids, such as formic, acetic, propionic, oxalic, amber, glycol, milk, apple, wine, lemon, ascorbic,

          Oxymaleic, dioxymaleic or pyruvic acid; Phenylacetic, benzoic, p-aminobenzoic, anthranil, p-oxybenzoic, salicylic or p-aminosalicylic acid; Metehansulfonic, ethanesulfonic, oxyethanesulfonic, ethylene sulfonic acid;

          Toluenesulfone, naphthalenesulfonic acids or sulfanilic acid; Methionine, tryptophan, lysine or arginine.



  The new compounds or their salts can be used as medicaments, e.g. B. find use 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 or parenteral administration. For the formation of the same substances come into question that do not react with the new compounds, such. B.

   Water, gelatine, milk sugar, starch, magnesium stearate, talc, vegetable oils, benzyl alcohol, gum, polyalkylene glycols, petrolatum, cholesterol or other known pharmaceutical carriers. The pharmaceutical prep can, for. B. as tablets, coated tablets or in liquid form as solutions, suspensions or emulsions.

   If necessary, they are starred and / or contain auxiliary substances such as preservatives, stabilizers, wetting agents or emulsifiers, salts for changing the osmotic pressure or buffers. They can also contain other therapeutically valuable substances. The preparations can be obtained by conventional methods.



  If the starting materials necessary for carrying out the reactions mentioned are not known, they can be obtained by the usual methods.



  The starting materials can also be formed under the reaction conditions or used in the form of a salt.



  The temperatures: are given in the following examples in degrees Celsius.



  <I> Example 1 </I> 12.0 g of 2-hydrazino-4,6-bis-diethylamino-1,3,5-triazine and 8.5 g of isonicotinic acid chloride'-hydrochloride are suspended in 100 cm3 of ethyl acetate and heated to boiling on the water bath. A solution of 10 g of triethylamine in 50 cm3 of ethyl acetate is added dropwise to the hot suspension, and the mixture is then heated for a further 5 hours. The resulting triethylamine hydrochloride shaves off as crystals.

    The mixture is cooled, washed neutral with water, with 2N sodium bicarbonate solution and again with water. The dried ethyl acetate solution is completely evaporated.

   The oily residue crystallizes on cooling and seeding. This gives (2- (2 'isonicotinoylhydrazino) -4,6-bis-diethylamino-1,3,5-triazine of the formula:

    
EMI0002.0067
         in white crystals that melt at 155-156.5. <I> Example 2 </I> 12.0 g of 2-hydrazino-4,6 = bis-diethylamino-1,3,5-triazine and 8.5 g of nicotinic acid chloride hydrochloride are suspended in 100 cm3 of ethyl acetate and brought to the boil This hot suspension is treated dropwise with a solution of 10 g of triethylamine in 50 cm3 of ethyl acetate within 30 minutes and then heated for a further 1.5 hours.

   The resulting triethylamine hydrochloride crystallizes out. The mixture is cooled, washed neutral with water, with 2N sodium bicarbonate solution and with water. The dried ethyl acetate solution is filtered through activated charcoal and evaporated completely.

   The thick liquid residue slowly crystallizes on cooling and is recrystallized from ether / petroleum ether or benzene / petroleum ether. The 2- (2 'nicotinoylhydrazino) -4,6-bis, diethylamino-1,3,5-triazran of the formula is obtained in this way
EMI0002.0092
    in white crystals that melt at 115-116.

      <I> Example 3 </I> 31.1 g of 2-hydrazino-4,6 = bis-d'iäthylamino-1,3,5-triazine and 17.4 g of picolinic acid chloride hydrochloride are suspended in 300 cm3 of ethyl acetate and heated the mixture on the water bath while stirring to boiling.

   A solution of 24.8 g of triethylamine in 40 cm3 of ethyl acetate is added dropwise to the hot, stirred suspension and the mixture is then heated for a further 5 hours. The mixture is cooled, washed first with water, then with dilute soda solution and again with water until neutral. The getrock Nete ethyl acetate solution is completely evaporated and the oily residue 'recrystallized in ethyl acetate / petroleum ether.

   The 2- (2'-picolinoyl-hyd'razino) -4,6 bis-diethylamino-1,3,5-triazine of the formula is obtained in this way
