More particularly the present invention provides compounds formula I, wherein Rj. is alkyl (1-4 C), halogen with an atomic number of 9 to 35 or amino optionally mono- or disubstituted by alkyl (1-4 C), R2 and R3 independently of one another are hydrogen or alkyl (1-4 C) and R4 is hydrogen, hydroxy, alkyl (1-4 C), alkoxy (1-4 C) or halogen with an atomic number of 9 to 35, in free base or acid addition salt form, hereinafter referred to as new compounds. - 2 - 100-7825 Insofar as above-defined alkyl or alkoxy groups are present in the new compounds, these preferably have one or two carbon atoms and especially signify methyl or methoxy.
The imidazolylmethyl radical is preferably in position 2 of the pyridine.
Rj. is preferably methyl. R2 and R3 are preferably each hydrogen. R4 is preferably hydrogen. The compound of Example 1 is preferred.
In a particular group of new compounds, Rj. is alkyl (1-4 C), R2 and R3 independently of one another are hydrogen or alkyl (1-4 C) and R4 is hydrogen, alkyl (1-4 C) or halogen with an atomic number of 9 to 35.
In accordance with the invention, the new compounds are obtained by reacting a compound of formula II, wherein R4 is defined as above, and X is halogen, with a compound of formula III, wherein Rj. , R2 and R3 are defined as above, - 3 - 100-7825 and recovering the resulting compound of formula I in free base form or in acid addition salt form.
The reaction of the compound of formula II with the compound of formula II may take place in known manner, in a solvent which is inert under the reaction conditions, e.g. in dimethylformamide or a lower alcohol. In formula II, X is preferably chlorine.
Working up of the reaction mixtures obtained and purification of the compounds of formula I thus produced may take place in accordance with known methods.
The compounds of formula I may be present in free form or in the form of their acid addition salts. Acid addition salts may be produced from the free bases in known manner, and vice versa.
The starting compounds of formulae II and III are known or may be produced in accordance with known processes, resp. analogously to known processes.
The compounds of formula I and their physiologically acceptable salts, hereinafter referred to as compounds according to the invention, exhibit interesting pharmacological activities and may therefore be used as pharmaceuticals.
In the sleep/wake cycle of the long-term implanted rat [for the method, see J.-M. Vigouret et al., J. Pharmacol 10, 503 (1978)], the compounds according to the invention when administered at 1 to 100 mg/kg p.o. effect an increase in vigilance by prolonging the wake phases. 103229/2 The present invention relates to imidazolylmethyl-pyridines, their production, their use as pharmaceuticals and pharmaceutical compositions containing them.
USP 4,230,714 discloses imidazolylmethyl-pyridines and -quinolines unsubstituted at the 2-positio of the imidazole moiety. Whereas these compounds are useful in treating ischemic heart disease stroke and migraine, the 2-substituted imidazoles of the present invention exhibit an unexpecte pharmacological profile indicative of central activity.
More particularly the present invention provides compounds formula I, wherein derlined . IX.1992 C) in free base or acid addition salt form, hereinafter referred to as new compounds. - 5 - 100-7825 In accordance with the foregoing, the present invention also provides a compound according to the invention, for use as a pharmaceutical, e.g. for the treatment of senile dementia, Alzheimer's disease and further degenerative diseases such as Huntington's chorea, Morbus Parkinson, Steel-Richardson syndrome, tardive dyskinesias, hyperkinesia, acute confusion disorders, Down's syndrome, myasthenia gravis and Friedrich's ataxia, and for the treatment of depression.
The present invention furthermore provides a pharmaceutical composition comprising a compound according to the invention in association with at least one pharmaceutical carrier or diluent. Such compositions may be manufactured in conventional manner. Unit dosage forms contain, for example, from about 0.25 mg to about 50 mg of a compound according to this invention.
The following examples illustrate the invention. The temperatures are given in degrees Celsius and are uncorrected. - 6 - 100-7825 EXAMPLE 1; [2-(2-methylimidazol-l-yl)methyl]pyridine 9.7 g (75 mM) of 2-(chloromethyl)pyridine and 42 g (512 mM) of 2-methyl-imidazole are suspended in 40 ml dimethylformamide, then stirred for 3 hours at 105 °. The dimethylformamide is distilled off and the crystalline residue is diluted with ethyl acetate and a little hexane. Following filtration, the mother solution is concentrated by evaporation and the dimethylformamide distilled off, and then shaken out several times between water and methylene chloride. 10.3 g of the oily title compound are obtained. 9.3 g of the obtained base in ethanol are mixed with 12.7 g of fumaric acid. The resulting bis(base)-tris(hydrogen fumarate)crystallizes from ethanol/ethyl acetate and is recrystallized once from ethanol/ethyl acetate. It is uniform upon thin-layer chromatography and melts at 109 - 110 °.
The following [2-(imidazol-l-yl)methyl] pyridines are produced analogously to example 1: fumarate dihydrochloride - 7 - 100-7825 well as the following [4-(imidazol-l-yl)methyl]pyridine: fumarate
