optionally in the form of the alkali metal, alkaline earth metal or ammonium salts and optionally in the presence of solvents.
The starting compounds of the formulae (II) and (III) are known or can be prepared by known methods.
The process for preparing the compounds of the formula (I) is preferably carried out using diluents. Practically all inert organic solvents are suitable for use a6 diluents in this context. The solvents preferably include aliphatic and aromatic, optionally halogenated hydro~
carbons, such as pentane, hexane, heptane, cyclohexane, petroleum ether, benzine, ligroin, benzene, toluene, xylene, methylene chloride, ethylene chloride, chloro-form, carbon tetrachloride, chlorobenzene and o-dichloro-benzene, ethers, such as diethyl ether, dibutyl ether,glycol dimethyl ether and diglycol dimethyl ether, tetrahydrofuran and dioxane, ketones, such as acetone, methyl ethyl ketone, methyl isopropyl ketone and methyl isobutyl ketone, esters, such as methyl acetate and ethyl acetate, nitriles, such as, for example, acetonitrile and propionitrile, amides, such as, for example, dimethyl-for ~ de, dimethylacet~m;de and N-methylpyrrolidone, as well as dimethyl sulphoxide, tetramethylene sulphone and hexamethylphosphoric triamide.
~ 25 Acid-binding agents which are customarily utilizable for ;~ reactions of this nature may be employed as acid ~ acceptors. Those which are preferable are alkali metal ~ , . ~ . .
21383~1 hydrides and alkaline earth metal hydrides, such as lithium, sodium, potassium and calcium hydride, alkali metal hydroxides and alkaline earth metal hydroxides, such as lithium, sodium, potassium and calcium hydroxide, alkali metal carbonates and hydrogen carbonates and alkaline earth metal carbonates and hydrogen carbonates, such as sodium carbonate or sodium hydrogen carbonate and potassium carbonate or potassium hydrogen carbonate, as well as calcium carbonate, alkali metal acetates, such as sodium and potassium acetate, alkali metal alcoholates, such as sodium and potassium tert-butoxide, and, additionally, basic nitrogen compounds, such as tri~
methylamine, triethylamine, tripropylamine, tributyl-amine, t.riisobutylamine, ethyldiiso-propylamine, ethyldicyclohexylamine, N,N-dimethylbenzyl-amine, N,N-dimethyl-aniline, pyridine, 2-methyl-, 3-methyl-, 4-methyl-, 2,4-dimethyl-, 2,6-dimethyl-, 2,6-dimethyl-, 2-ethyl-, 4-ethyl- and 5-ethyl-2-methyl-pyridine, 1,5-diazabicyclo-[4.3.0]-non-5-ene (DBN), 1,8-diazabicyclo-[5.4.0~-undec-7-ene (DBU) and 1,4-diaza-bicyclo-t2.2.2]-octane (DABCO).
The reaction temperatures can be varied over a relatively wide range. In general, temperature of between 0C and 100C, preferably temperatures of between 10C and 80C, are employed.
In general, the process is carried out under standard pressure. However, it is also possible to carry it out under elevated or reduced pressure.

21~8331 For carrying out the process, the starting compounds ~ A .:
which are required in each case are generally employed in approximately equimolar quantities. However, it is also possible to use one of the two components employed in 5 each case in a relatively large excess. In general, the ~ ;
reaction is carried out in a suitable diluent in the presence of an acid acceptor, and the reaction mixture is stirred for several hours at the temperature which is required on each occasion. The working up is in each case effected in accordance with the customary methods (cf.
the preparation examples). -~
In most cases, the compounds result in the form of oils, some of which cannot be distilled without decomposing;
however, these oils can be freed of the remaining vola~
tile constituents, and in this way purified, by so-called ~incipient distillation~, i.e. by being heated for a relatively long time, under reduced pressure, at mode-rately elevated temperatures. They are characterized on `-the basis of their refractive indices. `-The efficacy of the compounds of the formula (I) in the treatment and prevention of disorders of cerebral function is verified using an animal model which is based on spatial memory. In this test, originally described by Morris (R.G.M. Morris, J. Neurosci. Methods 11: 47-60, 1984), rats have to learn to locate a platform which they cannot see and which represents the only possible route of escape from a pool of water. For this, the animals (young, adult male rats, approximately 3 months old) are . ': ~:
TP 102 - 9 - ~
21~8331 given 4 training runs a day over a period of 3 days. The latency to locate the platform, and the distance covered, are the parameters which are measured.
As training progresses, both the escape latency and the distance swum diminish as the result of the acquisition of a strategy for spatially locating the goal. The effect of test substances in improving cognitive power is manifested in an acceleration of the time required for the learning process, i.e. the learning curve becomes steeper. Test substances are administered once a day (60 min prior to the first training run). Control animals receive an equivalent quantity of the vehicle.
":
At the end of the training phase, i.e. once the 12th training run has been completed, the platform is taken out of the water and it is investigated, in a further swimming experiment, whether the experimental animals look for the platfoxm in a defined naxrow area around the training position of the platform (retention test). - -~-The test results demonstrate that the described compounds have a positive influence both on the learning behaviour of the animals and on the retention of that which has been learnt. The esters described can, therefore, be used both for the therapeutic and the preventive treatment of cognitive disturbances in general, and of dementias of the Alzheimer type in particular.
The efficacy of the compounds of the formula (I) in the ~- -treatment and prevention of depressions is verified using '' ~
' ~ ~:
. ~' the "Rat Forced Swimming Test". This behavioural model was described for the first time by Porsolt et al. (R.D.
Porsolt, M. Le Pichon, M. Jalfre, Nature 266: ~30-732, 1977), and is nowadays a generally recognized in-vivo screening model for identifying novel antidepressants. It is based on the observation that, in a situation where there is no escape, rats persist in an immobile attitude ("behavioural despair"). In a pretest session, young adult rats (3-4 months old) are placed individually for 20 min in glass cylinders (height 40 cm, diameter 20 cm) which are filled with water to a height of 15 cm.
24 h after this pretest session , the animals are once again transferred into the cylinders and the duration of immobility is measured over a period of 5 min. The described esters are administered in the time interval between the two swimming sessions . Controls are given the vehicle.
In an analogous manner to clinically active antidepres~
sants described in the literature, the compounds of the formula (I) decrease the duration of immobility and lead to behavioural activation. On the basis of these results, the tescribed compounds are also suitable for use in the treatment of emotional disturbances, in particular of depression.

In general, it has been found to be advantageous to administer quantities of about 0.001 to 1 mg/kg, preferably 0.01 to 0.5 mg/kg, of body weight in order to achieve effective results in the case of intravenous administration, while, in the case of oral ":-. : .' ' . '' ':

administra~ion, the dosage is about 0.01 to 20 mg/kg, preferahly 0.1 to 10 mg/kg, of body weight. ;~
Despite this, it can, where appropriate, be necessary to deviate from the said quantities, depending on the body weight and the nature of the route of admlnistration, on the individual reaction to the medicament, on the nature of its formulation and on the time or interval at which administration -is effected. Thus, in some cases, it can be sufficient to administer less than the abovementioned lowest quantity while, in other cases, the said upper limit has to be exceeded. Where relatiyely large quantities are being administered, it can be advisable to divide these into several smaller doses given over -~ --the course of the day.
The invention also extends to a commercial package containing, as active pharmaceutical ingredient, a compound of the invention, together with instructions for its use for the treatment of diseases of the cognitlve function and depression.

The starting compounds of the formulae (II) and (III) are known or can be prepared by known methods.
The process for preparing the compounds of the formula (I) is preferably carried out using diluents. Practically all inert organic solvents are suitable for use a6 diluents in this context. The solvents preferably include aliphatic and aromatic, optionally halogenated hydro~
carbons, such as pentane, hexane, heptane, cyclohexane, petroleum ether, benzine, ligroin, benzene, toluene, xylene, methylene chloride, ethylene chloride, chloro-form, carbon tetrachloride, chlorobenzene and o-dichloro-benzene, ethers, such as diethyl ether, dibutyl ether,glycol dimethyl ether and diglycol dimethyl ether, tetrahydrofuran and dioxane, ketones, such as acetone, methyl ethyl ketone, methyl isopropyl ketone and methyl isobutyl ketone, esters, such as methyl acetate and ethyl acetate, nitriles, such as, for example, acetonitrile and propionitrile, amides, such as, for example, dimethyl-for ~ de, dimethylacet~m;de and N-methylpyrrolidone, as well as dimethyl sulphoxide, tetramethylene sulphone and hexamethylphosphoric triamide.
~ 25 Acid-binding agents which are customarily utilizable for ;~ reactions of this nature may be employed as acid ~ acceptors. Those which are preferable are alkali metal ~ , . ~ . .
21383~1 hydrides and alkaline earth metal hydrides, such as lithium, sodium, potassium and calcium hydride, alkali metal hydroxides and alkaline earth metal hydroxides, such as lithium, sodium, potassium and calcium hydroxide, alkali metal carbonates and hydrogen carbonates and alkaline earth metal carbonates and hydrogen carbonates, such as sodium carbonate or sodium hydrogen carbonate and potassium carbonate or potassium hydrogen carbonate, as well as calcium carbonate, alkali metal acetates, such as sodium and potassium acetate, alkali metal alcoholates, such as sodium and potassium tert-butoxide, and, additionally, basic nitrogen compounds, such as tri~

The reaction temperatures can be varied over a relatively wide range. In general, temperature of between 0C and 100C, preferably temperatures of between 10C and 80C, are employed.
In general, the process is carried out under standard pressure. However, it is also possible to carry it out under elevated or reduced pressure.

21~8331 For carrying out the process, the starting compounds ~ A .:
which are required in each case are generally employed in approximately equimolar quantities. However, it is also possible to use one of the two components employed in 5 each case in a relatively large excess. In general, the ~ ;
reaction is carried out in a suitable diluent in the presence of an acid acceptor, and the reaction mixture is stirred for several hours at the temperature which is required on each occasion. The working up is in each case effected in accordance with the customary methods (cf.
the preparation examples). -~
In most cases, the compounds result in the form of oils, some of which cannot be distilled without decomposing;
however, these oils can be freed of the remaining vola~
tile constituents, and in this way purified, by so-called ~incipient distillation~, i.e. by being heated for a relatively long time, under reduced pressure, at mode-rately elevated temperatures. They are characterized on `-the basis of their refractive indices. `-The efficacy of the compounds of the formula (I) in the treatment and prevention of disorders of cerebral function is verified using an animal model which is based on spatial memory. In this test, originally described by Morris (R.G.M. Morris, J. Neurosci. Methods 11: 47-60, 1984), rats have to learn to locate a platform which they cannot see and which represents the only possible route of escape from a pool of water. For this, the animals (young, adult male rats, approximately 3 months old) are . ': ~:
TP 102 - 9 - ~
21~8331 given 4 training runs a day over a period of 3 days. The latency to locate the platform, and the distance covered, are the parameters which are measured.
As training progresses, both the escape latency and the distance swum diminish as the result of the acquisition of a strategy for spatially locating the goal. The effect of test substances in improving cognitive power is manifested in an acceleration of the time required for the learning process, i.e. the learning curve becomes steeper. Test substances are administered once a day (60 min prior to the first training run). Control animals receive an equivalent quantity of the vehicle.
":
At the end of the training phase, i.e. once the 12th training run has been completed, the platform is taken out of the water and it is investigated, in a further swimming experiment, whether the experimental animals look for the platfoxm in a defined naxrow area around the training position of the platform (retention test). - -~-The test results demonstrate that the described compounds have a positive influence both on the learning behaviour of the animals and on the retention of that which has been learnt. The esters described can, therefore, be used both for the therapeutic and the preventive treatment of cognitive disturbances in general, and of dementias of the Alzheimer type in particular.
The efficacy of the compounds of the formula (I) in the ~- -treatment and prevention of depressions is verified using '' ~
' ~ ~:
. ~' the "Rat Forced Swimming Test". This behavioural model was described for the first time by Porsolt et al. (R.D.
Porsolt, M. Le Pichon, M. Jalfre, Nature 266: ~30-732, 1977), and is nowadays a generally recognized in-vivo screening model for identifying novel antidepressants. It is based on the observation that, in a situation where there is no escape, rats persist in an immobile attitude ("behavioural despair"). In a pretest session, young adult rats (3-4 months old) are placed individually for 20 min in glass cylinders (height 40 cm, diameter 20 cm) which are filled with water to a height of 15 cm.
24 h after this pretest session , the animals are once again transferred into the cylinders and the duration of immobility is measured over a period of 5 min. The described esters are administered in the time interval between the two swimming sessions . Controls are given the vehicle.
In an analogous manner to clinically active antidepres~
sants described in the literature, the compounds of the formula (I) decrease the duration of immobility and lead to behavioural activation. On the basis of these results, the tescribed compounds are also suitable for use in the treatment of emotional disturbances, in particular of depression.
