  The invention relates to a method for the production of new, therapeutically effective basic esters of 5,5-dialkylacridan-10-carboxylic acids, which may contain one or more benzene nuclei of the acridane structure Can carry substituents.



  The process according to the invention is carried out in such a way that the corresponding 5,5-dialkylacridane-10-carboxylic acid and an amino alcohol or their functional derivatives are esterified with one another.



  The most expedient procedure here is to react the basic alcohol, optionally as a metal alcoholate or in the presence of an inorganic or organic base, with the 5,5-dialylacridan-10-carboxylic acid halide in question, the The reaction runs according to the following formula:

    
EMI0001.0023
    R represents a divalent organic radical; R1, R2, R3 and R4 are identical or different, straight or branched aliphatic radicals, of which R3 and R4 also form a heterocyclic ring, optionally including a further hetero atom;

      can be joined together, and X1, X2, X3 and X4 can be the same or different and hydrogen, halogen or other substituents such as alkyl, trifluoroalkyl, aryl, carboxy, carbethoxy, nitro, amino ,

          Thio or alkylth'io groups represent.



  The compounds obtainable according to the invention show rubbed other pharmacodynamic properties, in particular local anesthetic, anticonvulsant, tremorine and reserpine antagonistic effects. The 5,5-dialkylaeridan used as starting material, also not yet described:

  -10- carboxylic acid chlorides are accessible, for example, by reacting the 5,5-dialkylacridane in question with phosgene.



  <I> Example 1 </I> The 5,5-dialkyl-acridane-10-carboxylic acid chloride used for the esterification can be obtained in the following manner: 10.5 g of 5,5-dimethylaeridane are mixed with 6 g of phosgene and 80 cm 3 of toluene heated to 115 ° C. in a pressure tube for 8 hours. The cooled solution is filtered and freed from the solvent by distillation.

   The residue (15 g) contains crude 5,5-dirnethylacridane-10-carboxylic acid chloride, which is purified by crystallization from gasoline (boiling point 110-140 ° C.). M.p. 141.5-143 C.

       Then. 5.5 g of the acid chloride used as the starting material are added to the mixture and the mixture is refluxed for a further 12 hours, whereupon it is filtered and the filtrate with 50 cm3 0,

  Shakes out 5N HCl. From the aqueous extract, which has been purified by shaking out several times with ether, the 5,5-dimethylacridane-10-carboxylic acid (2-dimethylaminoethyl) ester is obtained as a free one by adding the equivalent amount of sodium hydroxide solution, extracting it with ether and evaporating the extract Base in the form of a light oil.

   By neutralization with alcoholic HCl, a water-soluble hydrochloride is formed, which can be recrystallized from alcohol-ether (2: 1). M.p. 206-207 C. From yield 80-90%.
