Definitions
- the invention relates to a compound, 3- ⁇ 2- [4- (6-fluoro-benzo [d] isoxazol-3-yl) -3,6-dihydro-2H-pyridin-1-yl] -ethyl ⁇ -2-methyl-6, 7,8, 9-tetrahydropyrid- [1,2-a] pyrimidin-4-one, of formula (I):
- EP 0 196 132 describes 3- piperidinyl-1,2-benzoisoxazoles of formula (II) with antipsychotic properties.
- EP 0037265 describes 3 - [(l- piperidinyl) -4H-pyrido [1,2-a] pyrimidin-4-ones of formula (III)
- R can be H, alkyl, OH, RO or CH, OH at positions 2,3 or 4 of the piperidine ring, useful as cardiovascular agents and acting on the central nervous system.
- the compound of formula (I), object of this invention differs from the compounds known so far by the presence of a double bond between positions 3 and 4 of the piperidine ring and by their pharmacological activity.
- the invention also provides a pharmaceutical composition
- a pharmaceutical composition comprising the compound of formula (I) or a pharmaceutically acceptable salt thereof, together with a pharmaceutically acceptable diluent.
- the composition is preferably for human use, in the form of tablets, capsules, injectables or suspension, its use being particularly remarkable in the treatment of psychotic diseases.
- the compound of formula (I) can be obtained by a process consisting in the reduction of the pyridinium salt of formula (IV)
- the reduction of the pyridinium salt of formula (IV) can be conveniently carried out with a metal borohydride, such as sodium borohydride, in a suitable protic solvent, such as water, alkali or carboxylic acids.
- a metal borohydride such as sodium borohydride
- a suitable protic solvent such as water, alkali or carboxylic acids.
- the intermediates and starting compounds that are used in the process of the present invention are known products or can easily be prepared from known products.
- the intermediates of formula (IV) can be easily prepared by N-alkylation of the pyridine of formula (V) with a reagent of formula (VI), in which it represents a suitable leaving group such as, for example, a halide or a sulphonate
- This N-alkylation reaction is carried out in a solvent inert to the reaction, such as 4- methyl-2-pentanone, acetonitrile, N-methylpyrrolidone or N, N-dimethylformamide, optionally at somewhat elevated temperature and adding iodide potassium as catalyst.
- a solvent inert such as 4- methyl-2-pentanone, acetonitrile, N-methylpyrrolidone or N, N-dimethylformamide, optionally at somewhat elevated temperature and adding iodide potassium as catalyst.
- the pyridine of formula (V) can be obtained by cyclization of the oxime (VII) in an inert solvent, such as tetrahydrofuran, dioxane or N, N-dimethylformamide and in the presence of an appropriate base, such as a carbonate alkali or an alkali metal hydride or alkoxide.
- an inert solvent such as tetrahydrofuran, dioxane or N, N-dimethylformamide
- an appropriate base such as a carbonate alkali or an alkali metal hydride or alkoxide.
- the pyridine of formula (V) can also be obtained by delation of the acetylated derivative of formula (VIII) from the oxime of formula (IX) (L. Davis et al., Drug Design and Discovery, 8, 225-240 (1992))
- the ketone of formula (X) precursor of (VII) can be obtained by acylation of Friedel-Crafts of 1,3-difluorobenzene with isonicotinoyl chloride (FJ, Villani et al., J. Or. Chem. H, 249 (1952) ))
- the ketone of formula (XI) precursor to the oxime of formula (IX) can be obtained by reaction of Fries, from 3-fluorophenol and isonicotinoyl chloride.
- Preferred pharmaceutically acceptable salts are acid addition salts.
- the pharmaceutically acceptable addition salts of the compounds of formula (I) are those formed from acids that form non-toxic addition salts, counted With pharmaceutically acceptable anions.
- the salts may be derived from inorganic acids, such as hydrochloric, hydrobromic, sulfuric or nitric acids, or from organic acids, such as lactic, succinic, oxalic, maleic, etc.
- the salts can be obtained by conventional procedures, such as mixing solutions containing equimolecular amounts of the free base and the desired acid.
- the salt formed is separated by filtration, if it is insoluble, or by evaporation of the solvent.
- the compound of formula (I) and its pharmaceutically acceptable salts are very active as antipsychotics.
- H-prazosin binds with high affinity to ⁇ -1 adrenergic receptors of rat cerebral cortex.
