     FIELD OF THE INVENTION 
     The present invention relates to novel and pharmaceutically useful condensed thiophene compounds or salts thereof and pharmaceutical uses thereof, and further synthetic intermediates for said condensed thiophene compounds. 
     BACKGROUND OF THE INVENTION

No. 4,735,940, column 39, lines 50-51 and (6) Journal of Heterocyclic Chemistry, vol. 13, pp. 1347-1349 (1976). ##STR2## 
     On the other hand, compounds having antipsychotic activity are known by patent publications such as JP-A S60-84282, JP-A S59-227882, JP-A S58-90583, JP-A S63-132887, JP-A S63-183576, JP-A H1-199967 and JP-A H4-308584. 
     Antipsychotic drugs introduced in 1950&#39;s have been played a large role in treating schizophrenia. 
     In 1960&#39;s &#34;dopamine hypothesis&#34; concerned with schizophrenia has been suggested (Carlsson, A. et al, Acta. Pharmacol. Toxicol. 20, 140-144 (1963)) and the strong correlation between the affinity of antipsychotic drugs for D 2  receptors in striatum and the average clinical dose hive been reported (Seeman, P. et al, Nature, 261,717-719 (1976), Creese, I. et al, Science, 192,481-483 (1976)). After that, the concept of the development of anti psychotic drugs was the blockade of D 2  receptors. However, typical antipsychotic drugs are effective for the treatment of the positive symptoms such as hallucination and delusions, but not effective for that of the negative symptoms such as apathy and social withdrawal (Zubin, J. et al, Comprehensive Psychiatry, 26, 217-240 (1985)). And the extrapyramidal side-effect (EPS: dystonia, akathidia, tardive dyskinesia) and the elevation in the level of serum prolactin in the acute and chronic treatment of typical antipsychotic drugs are the serious problems for patients. 
     From these points of view, the development of atypical antipsychotic drugs, produce fewer EPS and are more effective than typical antipsychotic drugs in treating schizophrenia, is desired. 
     The profile of atypical antipsychotic drug are as follows. 
     1) It is effective for both positive and negative symptoms. 
     2) It produces fewer EPS. 
     3) It has no side-effect of internal secretion. 
     1. Merits by addition of 5-HT 2  receptor antagonistic activity: 
     In clinical study, it has been reported that the selective 5-HT 2  antagonist ritanserin ameliorates negative symptoms and reduces the incidence of EPS caused by typical antipsychotic drug therapy (Bersani, G. et al, Curr. Ther. Res., 10, 492-499 (1986)). And in preclinical study, it has also been reported that 5-HT 2  antagonists reduced catalepsy induced by haloperidol (Hicks, P. B., Life Sci., 47, 1609-1615 (1990)). On the other hand, syndrome malin induced by neuroleptics is the unbalance of dopaminergic and serotonergic activity in the center of the regulation of temperature has been proposed (Yamawaki, N., Sinkeiseisinyakuri, 11, 17-24 (1989). Therefore, it is expected that additional 5-HT 2  receptor antagonism reduces the syndrome malin. 
     Risperidone has extremely potent 5-HT 2  and potent D 2  receptor antagonistic properties (Janssen, P. A. J. et al, J. Pharmacol. Exp. Ther. 244, 685-693 (1988)), and has revealed a clinical profile that is distinct from that of existing neuroleptics. Risperidone proved to be an effective antipsychotic, with low EPS liability and with beneficial effects on the negative symptoms of schizophrenia (The 1st International Risperidone Investigator&#39;s Meeting (Conference Review), Paris (France), Mar. 9-10, 1992), but it has not a character of atypical antipsychotic drug yet because EPS is appeared in high dose of risperidone and it has side-effect of internal secretion yet. 
     2. Merits by addition of 5-HT 1A  agonist: 
     5-HT 1A  agonist has been reported to be possible to make up for the disadvantage of typical antipsychotic drugs, because 5-HT 1A  agonist buspirone improved the depression and EPS caused by haloperidol therapy in clinical study (McMillen, B. A. et al, J. Pharma. Pharmacol., 40, 885-887 (1988)). And, it is supported to the above mentioned possibility that 5-HT 1A  agonist 8-OH DPAT and buspirone reverse catalepsy induced by haloperidol in preclinical study (Golf, D. C. et al, J. Clin. Psychopharmacol. 11, 193-197 (1991)), Invernizzi, R. W. et al, Neuropharmacology, 27, 515-518 (1988)). And then, amplification of antipsychotic effect by additional 5-HT 1A  agonistic activity is expected, because administration of 8-OH DPAT with D 2  antagonist inhibit conditioned avoidance response (CAR) more potent than that of D 2  antagonist only (Wadenberg, M. L. et al, J. Neural. Transm. 83, 43-53 (1991)). 
     3. The functional relationships of 5-HT 1A  receptors and 5-HT 2  receptors: 
     By the study of electrical physiology and biochemistry, it has been revealed that 5-HT 1A  and 5-HT 2  receptors regulate the serotonergic activity through the K channel (second messenger system in cell) (Bobker, H. H. et al, Trends Neurosci., 13, 169-173 (1990)). Stimulation of 5-HT 1A  receptor makes a hyperpolarization, and stimulation of 5-HT 2  receptor makes a depolarization. Therefore, both 5-HT 1A  agonist and 5-HT 2  antagonist inhibit the serotonergic activity, and the inhibition of serotonergic activity is amplified if 5-HT 1A  agonistic and 5-HT 2  antagonistic activities are occurred at the same time. This is supported by the preclinical pharmacological data that anxiolitic and antidepressant effects of 5-HT 1A  agonist are reinforced by addition of 5-HT 2  antagonist (Millan, M. J. et al, J. Neural. Transm. 83, 43-53 (1991)). 
     As mentioned above, it has been reported that the disadvantages of typical antipsychotic drugs are improved by addition of 5-HT 2  antagonistic and 5-HT 1A  agonistic activities to the typical antipsychotic drugs (D 2  antagonists). Especially, negative symptoms must be distinguished from depression, but in either symptoms the desired pharmacological effect is activation, and it is suggested that the addition of 5-HT 1A  agonistic activity, that improves the depression, improves the negative symptoms like 5-HT 2  antagonistic activity. 
     As mentioned above, the amplificational effect of serotonergic activity are expected by addition of both 5-HT 1A  agonist and 5-HT 2  antagonist, therefore it is expected that the addition of both 5-HT 1A  agonist and 5-HT 2  antagonist to D 2  antagonist is more effective to the negative symptoms than the addition of either of them to it. 
     SUMMARY OF THE INVENTION 
     The present inventors have found that novel condensed thiophene compounds have D 2 , 5-HT 2  antagonistic and 5-HT 1A  agonistic activities and are useful as potent antipsychotic drugs according with the above-mentioned purposes, and completed the present invention.

     The pharmacological activities of the compound of formula (I) were examined by a series of receptor binding tests, anti-apomorphine action and anti-ergometrine action as described below. 
     Experiment Example 1: Affinity for dopamine 2 receptor 
     A specific binding of dopamine 2 (D 2 ) receptor was tested according to the method described in Eur. J. Pharmacol. 46, 377 (1977). 
     A synaptosome fraction was separated from corpus striatum of 9-10 week-old Wistar rats, and suspended in 50 mM Tris-HCl buffer (pH 7.1) containing 120 mM sodium chloride, 5 mM potassium chloride, 2 mM calcium chloride, 1 mM magnesium chloride, 10 μM pargyline and 0.1% ascorbic acid for the experiment. 
     The test compound at several concentrations and tritiated spiperone (final concentration 0.2 nM) were added to the synaptosome suspension, and each mixture was incubated at 37° C. for 20 minutes. After the incubation, the mixture was filtered with suction through Whatman GF/B (trade mark) glass filter. The filter was washed with 50 mM Tris-HCl buffer (pH 7.7), and the radioactivity of the filter was measured by a liquid scintillation counter. Non-specific binding was determined in the presence of 10 -4  M (±)-sulpiride. The concentration necessary for 50% inhibition (IC 50 ) was determined on a graph, and inhibition constant (Ki value) was calculated. The results are shown in Table 1. 
     Experiment Example 2: Affinity for serotonin 2 receptor 
     A specific binding of serotonin 2 (5-H 2 ) receptor was tested according to the method described in Mol. Pharmacol. 21, 301 (1981). 
     A crude synaptosome fraction was separated from hippocampus of 9-10 week-old Wistar rats, and suspended in 50 mM Tris-HCl buffer (pH 7.7) for the experiment. The test compound at several concentration and tritiated ketanserin (final concentration 0.2 nM) were added to the synaptosome suspension, and each mixture was incubated at 37° C. for 20 minutes. After the incubation, the mixture was filtered with suction through Whatman GF/B (trade mark) glass filter. The filter was washed with 50 mM Tris-HCl buffer (pH 7.7), and the radioactivity of the filter was measured by a liquid scintillation counter. Non-specific binding was determined in the presence of 10 -5  M mianserin. The concentration necessary for 50% inhibition (IC 50 ) was determined on a graph, and inhibition constant (Ki value ) was calculated. The result are shown in Table 1. 
     Experiment Example 3: Affinity for serotonin 1A receptor

     Experiment Example 4: Anti-apomorphine action (in mouse) 
     Male dd mice at 3 per group were used for the experiment. The test compound was orally administered to the mice, and 60 minutes later, 0.5 mg/kg of apomorphine hydrochloride was subcutaneously administered. 
     the movement for 20 minutes from immediately after the administration of apomorphine hydrochloride was measured using Valimex (Columbus, USA). Each group was tested four times, and the amount of the test compound necessary to lower the movement by 50% than that of a control group was calculated from a graph and taken as ED 50 . The results are shown in Table 2. 
     Experiment Example 5: Anti-ergometrine action 
     Male ddY mice at 12 per group were used for the experiment. The test compound was orally administered to the mice, and 60 minutes later, 20 mg/kg of ergometrine maleate was intraperitoneally administered. The amount of the test compound necessary to vanish the head-twitch reaction for 10 minutes from immediately after the administration of ergometrine maleate was calculated as ED 50  value by Probit method.

     Experimental Example 6: Catalepsy Test 
     The method of Simon, P. et al (J. Pharm. Pharmacol., 22, 546, 1970) was utilized with a slight modification. 
     Catalepsy in rats was evaluated at the various time after oral administration of test drugs using a horizontal bar positioned 7 cm above the bench. Cataleptogenic activity was judged to be positive when the forepaws of the rats remained on the bar for more than 30 sec. Ten rats at each dose level were used to determine the ED 50  value required to induce catalepsy in 50% of the animals. 
     Experiment Example 7: Acute toxicity 
     Male ddY mice weighing 20-28 g were used at 10 per group. They were orally administered with the compound of Example 24 and observed for 5 days after the administration. The LD 50  (50% lethal dose) was 205 mg/kg. 
     The compounds of formula (I) were found to have high affinities for dopamine (D 2 ) receptor and serotonin (5-HT 1A , 5-HT 2 ) receptors according to the receptor binding assay using the radioligands. And they possessed D 2  antagonistic, 5-HT 2  antagonistic and 5-HT 1A  agonistic activities according to the inhibition of apomorphine-induced hyperactivity, ergometrine-induced head-twitches and forskolin-induced adenylate cyclase activity, respectively. Further they were found to have the inhibitory activity of spontaneous locomotor activity, methanphetamine-induced hyperactivity and conditioned avoidance responding. Therefore, these compounds will be effective for the positive symptoms such as hallucination and dellusion. And they were found to be effective for the forced swimming test, an indication of activation, and to have low cataleptogenic activity, an indication of the extrapyramidal side-effects. Therefore, these compounds will also be effective for the negative symptoms, such as apathy and social withdrawal. And they will be effective antipsychotic drugs with the potential for fewer extrapyramidal side-effects. The compounds of formula (II) are useful as synthetic intermediate for the compounds of formula (I). 
     When the compounds of formula (I) of the present invention are used as pharmaceuticals, a therapeutically effective amount of the compounds and adequate pharmacologically acceptable additives such as excipient, carrier, diluent and so on are mixed to be formulated into a form such as tablets, capsules, granules, syrups, injectable solutions, suppositories, dispersible powders or the like and are administered in the form mentioned above. The dosage may generally range about 5 to about 500 mg per day for an adult in a single dose or divided doses in the case of oral administration. 
     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention will be explained in more detail by the following examples, but these examples are not to be construed as limiting the present invention. The following compounds obtained can be identified by the various analysis such as NMR, IR, elemental analysis, mass spectrometry and so on. 
     Reference Example 1 
     To a solution of 171 g of 2-methylthiophene in 1500 ml of methylene chloride were added dropwise 500 g of tin(IV) chloride and 300 g of ethyl succinyl chloride under ice-cooling and the mixture was stirred for 1.5 hours. The mixture was poured into water, extracted with chloroform and the organic layer was washed with water, dried over magnesium sulfate and distilled away. To the residue was added isopropyl ether and the precipitated crystals were collected by filtration to give 299 g of white crystals. The resulting crystals were dissolved in 1600 ml of diethylene glycol and 264 g of 100% hydrazine monohydrate was add thereto and the mixture was stirred at 110° C. for 45 minutes. After cooling to 60° C., 445 g of potassium hydroxide was added thereto and the mixture was stirred at 140° C. for 1.5 hours. The mixture was poured into water, acidified with hydrochloric acid and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate and the solvent was distilled away. The residue was dissolved in 500 ml of acetic anhydride, 5 ml of phosphoric acid was added thereto and the mixture was refluxed with stirring for 80 minutes.
