These rings can be linked either through carbon or nitrogen. The term "halogen" means fluorine, chlorine, bromine or iodine. The compounds of the general formula (1) can be prepared by any suitable method known in the art and / or by the processes described below. It will be appreciated that where a particular stereoisomer of formula (1) is required, the synthetic process described in present can be used with the appropriate homochiral starting material and / or isomers maybe resolved from mixtures using conventional separation techniques (for example, HPLC). In the description and formulas below, variables such as R1 R2, R3, R4, s / -A, W, X, Y and Z are as defined in the foregoing, except where indicated otherwise. It will be appreciated that functional groups, such as amino, hydroxyl or carboxyl groups, present in the various compounds described below, and which are desired to be retained, may need to be in protected form before any reaction is initiated. In such examples, the removal of the protecting group may be the final step in a particular reaction. Suitable protecting groups for such functionality will be apparent to those skilled in the art. For specific details, see "Protectíve Groups in Organic Synthesis", Wiley Interscience, T W Greene, PGM Wuts. A process for preparing the compounds of the general formula (1), wherein W, X, Y or Z is N or C-Br and A is O or S (0) n, comprises cyclization with acid (e.g. toluenesulfonic) of a diol (2) which in turn can be obtained by reducing ketone (3) with a suitable reducing agent. (2) (3) The reduction of a keto amide of the general formula (3) can be carried out with reagents well known to those familiar in the art of synthetic organic chemistry. An example of a highly reactive reducing agent is lithium aluminum hydride, although reagents based on borane (for example borane complex, tetrahydrofuran) or reduction of sodium borohydride (for example with a nickel or cobalt salt link) can be equally effective. Likewise, the reduction of ketone in (3), for example with sodium borohydride, followed by cyclization with acid, for example with p-toluenesulfonic acid, then the final reduction of the amide group, for example with borane, also leads to compounds of the general formula (1). Ketones (3) can be prepared by the condensation of a carboxylic acid (4) or an active derivative of it, with an amine (5). The active acid derivatives of the formula (4) include, for example, acid anhydrides or acid halides, such as acid chlorides.
The coupling reaction can be performed using standard conditions for amidation reactions of this type. Thus, the reaction can be carried out in a solvent, for example an inert organic solvent such as an ether, for example a cyclic ether such as tetrahydrofuran, an amide, for example a substituted amide such as dimethylformamide, or a halogenated hydrocarbon. such as dichloromethane at low temperature, for example -30 ° C at room temperature, such as -20 ° C to 0 ° C, optionally in the presence of a base such as, for example, an organic base such as an amine, for example triethylamine or a cyclic amine such as N-methylmorpholine. Where an acid (4) is used directly, the reaction can be further carried out in the presence of a condensing agent, for example a diimide such as N, N-dicyclohexylcarbodiimide, advantageously in the presence of a triazole such as 1-hydroxybenzotriazole. Alternatively, the acid can be reacted with a chloroformate, for example ethyl chloroformate, before reaction with the amine (5). The acids (4) can be prepared by the Friedel-Crafts acylation of R2 with an anhydride (7). This reaction is carried out in an inert solvent (such as dichloromethane) in the presence of an acid catalyst.
Lewis (such as aluminum trichloride). (7) It is well recognized by those skilled in the art that such reactions can provide product mixtures and in turn that these mixtures can often be separated by flash column chromatography. For example, where Y = C-Br, W = X = Z = CH and R2 is phenyl, Friedel-Crafts acylation under the catalysis of aluminum trichloride provides two isomeric bromides (4a) and (4b). These can be easily separated by column chromatography and independently progress to the compounds of the general formula (1), wherein X or Y is C-Br, by the route described previously , The compounds of the general formula (1) wherein one of W, X, Y and Z is C-hal such as C-Br represent flexible intermediates which can be used for the preparation of other compounds of the general formula (1). For example, these compounds can be regularly converted to the corresponding nitrile (R3 = CN) either by reaction with cuprous cyanide in a dipolar aprotic solvent such as N-methylpyrrolidinone (? MP) or under conditions catalyzed by palladium. The nitrile can easily be converted, by hydrolysis, to the primary amides (R3 = CO? H2), esters and the corresponding carboxylic acids (CO2R5) or to the corresponding tetrazoles, by treatment with a suitable azide donor such as azide. of sodium or trimethylsilyl azide. In addition, the compounds of the general formula (1) wherein one of W, X, Y and Z is C-hal such as C-Br can be lithium with n-, sec- or tert-butyl lithium in an inert organic solvent such as an ether, for example a cyclic ether such as tetrahydrofuran, at a very low temperature, for example -78 ° C. The treatment with either a carbon (for example carbon dioxide, N, N-dimethylformamide or paraformaldehyde), sulfur (for example S02C12, followed by amidation, such as with ammonia) or nitrogen (diphenylphosphoryl azide, followed by reduction , as with REDAL) provides access, by subsequent derivation, to derivatives where R3 is C02R5, CO? (R5), CH2OR5, S02? (R4) 2,? R? COR4,? RxCOsRs or? R? CO? ( R5) 2. In addition, compounds of the general formula (1) wherein one or W, X, Y and Z is C-hal such as C-Br can be subjected to palladium catalyzed coupling reactions with carbon-based coupling partners. Thus, these compounds can be coupled to alkenes of the general type CH2 = CHR3 under Heck conditions, to alkynes of the general type CH = CHR3 under Sonogoshira conditions, or to metalloheterocycles, for example where the metal is tin, under Stille coupling conditions. This gives access to compounds where R3 is optionally substituted C2-C6 alkenyl or C2-Ce alkynyl, or a five-membered aromatic heterocycle containing 1-4 heteroatoms selected from? (such as in pyrrole, diazoles, triazoles or tetrazoles) and O (such as in furan, oxazoles or oxadiazoles). Such reactions of coupling ensure that the chains and rings are bonded through carbon. In addition to the examples described above, additional compounds of the formula (1) can be prepared by the interconversion of other compounds of the formula (1). Thus, for example, a compound wherein R3 is alkyl can be prepared by hydrogenation (using palladium on carbon in a suitable solvent, such as an alcohol, for example ethanol) of a corresponding compound wherein R3 is alkenyl. Any of the mixtures of final products or intermediates obtained can be separated at the bases from the physico-chemical differences of the constituents, in a known manner, in the final products or intermediates, for example by means of chromatography, distillation, fractional crystallization, or by forming a salt if appropriate or under possible circumstances. The compounds according to the invention exhibit inhibitory activities in vi tro with respect to the reuptake of monoamine (ie noradrenaline, serotonin and dopamine). The activity and selectivity of the compounds can be determined by the use of an appropriate monoamine reuptake assay. This invention also relates to a method of treatment for patients (including man and / or animals) mammals reproduced in the dairy, meat or skin industries or as pets) suffering from disorders or diseases that can be attributed to monoamine reuptake as previously described, and more specifically, a method of treatment involving the administration of the inhibitor of monoamine reuptake of the formula (1) as the active constituents. Therefore, the compounds of the formula (1) may be useful in the treatment of pain and vomiting. The pain and related conditions that can be treated include syndromes characterized by chronic pain and fatigue, fibromyalgia, chronic fatigue syndrome, complex regional pain syndrome, irritable bowel syndrome, facial pain and atypical chest pain.

Assay for Inhibition of Noradrenaline Reuptake Activity Synaptosomes (100 μg) are incubated for 20 min at 37 ° C with Ci 0. l [3 H] norepinephrine in the absence (control) or presence of the test compound or the reference compound in a regulated solution containing 118 M NaCl, 5 mM KCl, 2.5 mM MgSO 4, 1.2 mM NaH 2 PO 4, 25 mM NaHCO 3, 11 mM glucose, 10 μM EGTA and 50 μM ascorbic acid (pH 7.4 ). The base control activity is determined by incubating the same mixture for 20 min at 0 ° C in the presence of 10 μM protriptyline to block reuptake. After incubation, samples are rapidly filtered under vacuum through glass fiber filters (GF / B, Packard) and rinsed twice with ice-cold incubation buffer using a 96-cell cell harvester (Unifilter, Packard) to eliminate [3H] norepinephrine free. The filters are dried and the radioactivity retained is measured in a scintillation counter (Topcount, Packard) using a scintillation cocktail (Microscint 0, Packard). The results are expressed as a percentage inhibition of the reuptake control of [3 H] norepinephrine. The standard inhibitory reference compound is protriptyline, which is tested in each experiment in severe concentrations to obtain a curved inhibition of which its IC50 value is calculated.
