These compounds have valuable pharmacological properties, particularly a hypotensive, sedative, antitussive and/or antiphlogistic activity. Of the compounds described in British Patent No. 1321509, the compounds 2-amino-6-allyl-4,5,7,8- tetrahydro-6H-thiazolo[5,4-diazepine (Compound A) and 2- amino-6-(4-chloro-benzyl)-4,5,7,8-tetrahydro-6H- thiazolo[5,4-diazepine (Compound B) were subsequently investigated further. Thus, for Compound A (=B-HT 920), its affinity for .alpha.2-adrenoceptors (R. Hammer, W. Kobinger and L. Pichler, Europ. J. Pharmacol. 62, 277 (1980)); their use for treating angina pectoris (DE-A-2820808, L. Benedikter et al.); their agonistic effect on dopamine autoreceptors (N.-E. Anden et al., Naunyn-Schmiedeberg's Arch. Pharmacol. 321, 100 (1982) and J. Neural Transmission 57, 129 (1983)); their in vivo inhibition of endogenous dopamine synthesis in the brain (N.-E. Anden et al., Acta pharmacol. et toxicol. 52, 51 (1983)): their inhibition of prolactin levels in the blood (V. Brantl et al., EP-A-0195888); their effect as a post-synaptic dopamine agonist on the denervated dopamine receptor in the striatum and their use as drugs for treating Parkinsonism (O. Hornykiewicz, DE-A-3503963; and D. Hinzen, O. Hornykiewicz, et al., Europ. J. Pharmacol. 131, 75 (1986)) and their affinity for dopamine-D2 receptors (G. Griss, R. Hurnaus et al.; EFMC-IXth International Symposium on Medicinal Chemistry, Berlin (West), Sept. 14-18, 1986, Short Communication No. 64, Abstract page 114) and for the compound B (=B-HT 958), its .alpha.2-agonistic activity with a high pre/postsynaptic activity ratio (L. Pichler, H. Hortnagl and W. Kobinger, Naunyn- Schmiedeberg's Arch. Pharmacol. 320, 110 (1982)); its use in treating angina pectoris (DE-A-2820808, L. Benedikter et al.); its cardiovascular effects (W. Kobinger and L. Pichler, Europ. J. Pharmacol. 97, 67 (1984)); its central .alpha.2-antagonistic activity and its agonistic effect on dopamine autoreceptors in the brain (H. Hortnagl, L. Pichler, U. Holzer-Petsche, O. Hornykiewicz and W. Kobinger, Europ. J. Pharmacol. 106, 335 (1985); its hypotensive and heart rate lowering activity by the stimulation of dopamine receptors (probably located in the CNS) (M. J. Brown and D. Harland, Brit. J. Pharmcol. 87, 361 (1986)) and its affinity for .alpha.2- and D2-receptors (G. Griss, R. Hurnaus et al.; EFMC-IXth Intern. Symp. on Medicinal Chemistry, Berlin (West), Sept. 14-18, 1986 Short Communication No. 64, Abstract page 114) have been published. The aim of the invention was to discover new dopaminergics with more favourable properties, which, unlike the known compounds of general formula I, have a substantially reduced affinity for .alpha.2-adrenoceptors, so as to reduce the risk of .alpha.2-induced side effects (sedation, ataxia and hypotonia). The present invention thus relates to new 4,5,7,8-tetrahydro-6H-thiazolo[5,4-d]azepines of general formula II ##STR3## the acid addition salts thereof, and particularly for pharmaceutical use the physiologically acceptable acid addition salts thereof with inorganic or organic acids, the preparation and use thereof as pharmaceutical compositions. The new compounds have valuable pharmacological properties, namely selective effects on the dopaminergic system caused by stimulation of (predominantly D2) dopamine receptors. In addition, analgesic and anti- inflammatory effects and serotonin-2-antagonistic activities are also observed. The compounds according to the invention are particularly suitable for treating diseases of the central nervous system such as Parkinson's disease, hyperprolactinaemia and schizophrenia and also for treating cardiovascular diseases, in view of their pharmacological properties.

The starting compounds VI are obtained from the compounds VIII for example by reaction with bromine in glacial acetic acid in the presence of hydrogen bromide. The starting compounds IV are partly described in GB-A-1321509. The starting compounds of formulae XI to XV, XVII, XIX and XX are obtained from the compounds IV by reaction with the corresponding compounds with alkylation or reductive amination or acylation. The starting compounds XVI are obtained by reduction of the compounds XV for example using sodium borohydride. As already mentioned hereinbefore, the new compounds have valuable pharmacological properties, namely selective effects on the dopaminergic system which are achieved by stimulation of (predominantly D2) dopamine receptors. The compounds according to the invention are particularly suitable for treating diseases of the central nervous system such as Parkinson's disease, hyperprolactinaemia and schizophrenia, and also for treating cardiovascular diseases such as ischaemia and cardiogenic shock.

Billard et al., Life Sci. 35, 1885 (1984) and D. J. de Vries and P. M. Beart, Eur. J. Pharmacol. 109, 417 (1985)) Membrane Preparation Male rats (of the Chbb:Thom strain weighing about 200 g) were killed by a blow to the back of the neck. The brains were removed and dissected on ice. The striata were dissected out, weighed and homogenised in 25 volumes of tris buffer (50 mM tris-HCl, 1 mM EDTA, 5 mM MgCl.sub.2 and 1 mM ascorbic acid) for 30 seconds in an Ultra-Turrax at maximum speed, followed by 10 cycles in a Potter-Elvehjem at 1400 rpm. The pellet obtained after centrifuging at 50,000.times.g at 4.degree. C. for 15 minutes was again taken up in 25 ml of tris buffer and centrifuged under the above conditions. The supernatant was discarded and the pellet obtained was incubated in 25 ml of tris buffer at 37.degree. C. for 30 minutes and then centrifuged again at 50,000.times.g at 4.degree. C. for 15 minutes. Finally, the pellet obtained was mixed with tris buffer to obtain a homogenate dilution of 1:500 (based on the weight of the striata). Binding Assay 1 ml aliquots of the membrane preparation were incubated with 1 ml of a solution of 0.25 nM [.sup.3 H]-spiperone (0.75 GBq/mmol, Messrs.

The substances displace the radioligand in a biphasic manner which is typical of agonists; the D2-Ki values given (Ki=IC.sub.50 : (1+C.sub.L /K.sub.L), wherein C.sub.L and K.sub.L represent the concentration and dissociation constant, respectively, of the radioligand used (see Cheng and Prusoff in Biochem. Pharmacol. 22, 3099 (1973))) relate to the high-affinity form of the dopamine receptor. 2. Determination of the affinity for alpha-2 receptors by displacement experiments with [.sup.3 H] clonidine (Modified Method of B. Jarrott, W. J. Louis and R. J. Summers, Biochem.

DuPont NEN) and with increasing concentrations of the test substance (10.sup.-11 to 10.sup.-4 M). Incubation was ended by the addition of 5 ml of ice-cold tris buffer and filtration through Whatman GF/B filters. The filters were washed twice, each time with 5 ml of ice cold buffer. The radioactivity of the filters was determined by liquid scintillation measurement in Instagel(R) (Messrs. Canberra Packard). The non-specific binding was determined in the presence of 10.sup.-5 M of oxymetazoline (Sigma Chemical Co.).

Determining the affinity for serotonin-1A(5-HT1A) receptors by displacement experiments with [.sup.3 H]--8--OH-- DPAT. (Method of S. J. Peroutka, J. Neurochem. 47, 529 (1986), modified according to H. Gozlan et al., J. Receptor Research 7. 195 (1987)) Membrane Preparation A male rat (Chbb:Thom strain weighing about 200 g) was decapitated. The brain was removed and placed in ice-cold buffer (50 mmol/1 tris-HCl plus hydrochloric acid ad pH =7.4 at ambient temperature). The frontal cortex was dissected out; its moist weight was determined. It was homogenised in 40 times its volume of buffer (Polytron, position 6, 10 seconds), then centrifuged for 20 minutes at 45,000.times.g in the refrigerated centrifuge. The pellet was washed in 100 times its volume of buffer and centrifuged again as described above. The resulting pellet was resuspended in 40 times its volume of buffer and pre-incubated for 10 minutes at 37.degree. C. Sixty times the volume of buffer were added and centrifuging was carried out as above. The resulting pellet was washed with 100 times the volume of buffer and centrifuged as above. The pellet was resuspended in buffer (0.8 ml/10 mg) and briefly homogenised in the Polytron. This homogenised tissue was cooled in ice until ready for incubation. Binding Assay 0.8 ml of tissue homogenate (=10 mg moist weight) were incubated together with 0.1 ml of a solution of [.sup.3 H]-8-OH-DPAT (about 0.1 nmol/1 final concentration) and with 0.1 ml of a solution of the test substance (increase in concentration) for 30 minutes at ambient temperature (triple measurement). Incubation was stopped by rapid filtering through Whatman GF/B filters; rinsing was carried out twice, each time with 5 ml of ice cold buffer (Filter Prep, Messrs. Ismatec). The radioactivity of the filters was determined by liquid scintillation measurement. Non-specific binding was determined in the presence of 10.sup.-4 mol of serotonin. Data Analysis Specific binding is obtained from total binding minus non-specific binding. The averages of the three measurements were entered in a system of coordinates (abscissa (log.): concentration of test substance (mol/l), ordinate (lin.): radioactivity of the samples (.times.dpm). The IC.sub.50 value is the concentration which inhibits the specific bonding of [.sup.3 H]--8--OH--DPAT [=[.sup.3 H]-hydroxy-2-(di-n-propylamino)tetraline]by 50%. 4. Determining the affinity for serotonin-2(5-HT2)-receptors by displacement experiments with [.sup.3 H]-spiperone (Modified Method of S. J. Peroutka et al., Mol. Pharmacol 16, 700 (1979)) Membrane Preparation A male rat (Chbb:Thom strain, about 200 g) was decapitated. The brain was removed. The frontal cortex was dissected out and placed in ice cold 0.32 M saccharose solution; its moist weight was determined. It was homogenised in 10 times the volume (0.32 M) of saccharose solution for 1 minute at 800 rpm in a Potter S (made by Braun of Melsungen). The homogenised material was centrifuged for 10 minutes at 1000.times.g (=3,000 rpm with a rotor 8.times.38 ml) in a refrigerated centrifuge. The supernatant was decanted off and homogenised (Polytron, position 5, 1 minute); the sediment was discarded. 5 ml (=0.5 g moist weight) of the tissue suspension thus obtained were made up to 40 ml with buffer (50 mm tris-HCl; pH=7.7 at ambient temperature). Binding Assay 0.8 ml of the buffered homogenised tissue (=10 mg moist weight) were incubated with 0.1 ml of a solution of [.sup.3 H]-spiperone (about 0.2 nmol/1 final concentration) and with 0.1 ml of a solution of the test substance (increasing concentration) for 15 minutes at 37.degree. C. (triple measurement). Incubation was stopped by rapid filtering through a Whatman GF/B filter; rinsing was carried out 3 times, each time with 5 ml of ice cold buffer within a maximum of 10 seconds (Filter Prep Messrs. Ismatec). The radioactivity of the filters was determined by liquid scintillation measurement. The non-specific binding was determined in the presence of 10.sup.-4 mol/l ketanserine. Data Analysis The specific binding is obtained from the total binding minus the non-specific binding. The averages of the triple measurements are entered in a system of coordinates as in 1.3. The IC.sub.50 value is the concentration which inhibits the specific binding of [.sup.3 H]-spiperone by 50%.

Motility triggering in the mouse which has been treated 24 hours earlier with reserpine (Method of D. Hinzen et al., Europ. J. Pharmacol. 131. 75 (1986)) This test determines predominantly agonistic effects on the hypersensitive dopamine receptor. Description of Test Male mice are treated 24 hours before the experiment with 5 mg/kg i.p. reserpine. The animals are kept at 25.degree.-30.degree. C. and treated three times with 2 ml of a 5% glucose solution in tyrode s.c. (the first time when the reserpine is given, the second time in the evening of the pre-treatment day and the third time on the morning of the test day). Groups of 6 animals are given the test substance in a quantity of 5 mg/kg injected subcutaneously. (The injection volume is usually 0.1 ml/10 g of body weight). 30 minutes later the groups of animals are placed in the observation cages (measuring 42 x 24 x 8 cm) and fitted with an infrared lightbeam in order to measure their activity. The value measured is the frequency with which a group of 6 mice pass through the infra-red beam within 5 minutes ("running pulses/5 minutes"; mean at n=3; mean.+-.s.e.m. at n=6). 3 to 6 groups are tested for each substance. The control animals are given isotonic saline solution s.c.; they show minimal activity (<5 running pulses per 5 minutes). The standard substance A results in 50 running pulses every 5 minutes in a dosage of 3 mg/kg s.c.; Substance B is less effective than compound A; it results in 22 running pulses every 5 minutes at 5 mg/kg s.c. If complete dosage-activity curves are plotted, the DLi50 is taken as the dosage resulting in 50 running pulses every 5 minutes. Table 3 which follows shows the DLi50 values of compounds according to the invention.

Determining the post-synaptic dopaminergic activity in MPTP monkeys (Modified Method of R. S. Burns et al., Proc. Natl. Acad. Sci. 80. 4546 (1983)) Description of Experiment The neurotoxin 1-methyl-4-phenyl-1,2,3,6- tetrahydro-pyridine (MPTP) produces in humans and monkeys an irreversible syndrome which in its clinical, pathological, biochemical and pharmacological appearance is very similar to idiopathic Parkinson's disease (Markey et al., Nature 311, 464 (1984)). The reason for this similarity is that MPTP selectively destroys those dopaminergic nerve cells in the substantia nigra of the brain which are also lost by degenerative processes in Parkinson's disease. There is even some discussion that MPTP or an MPTP-like substance might be formed in the body and trigger Parkinson's disease (S. H. Snyder, Nature 311, 514 (1984)). Possibly because of the specific MPTP metabolism, the clinical formation of the MPTP-induced Parkinson syndrome has hitherto been detected only in humans and monkeys. The MPTP model produced in the rhesus monkey is therefore exceptionally suitable for testing the activity of post-synaptically acting dopamine agonists. For this purpose, rhesus monkeys were given MPTP in overall doses of up to about 6 mg/kg of body weight, until the following symptoms appeared: The animals were akinetic and unable to take water and food. They showed a typical bent posture; occasionally cataleptic states occurred. The extremities showed rigor, which was interrupted by clonic spasms during passive movement. Dopamine agonists such as B-HT 920 (=compound A), levodopa or apomorphine result in a temporary cessation of this phenomenon. Table 4 which follows shows the minimum doses (MED) of the compounds according to the invention which are required to alleviate the Parkinson's symptoms, their duration of effect and any side effects observed. It is clear that with the compounds according to the invention there is no sedative effect or ataxia at a dosage which is several times the MED, which can be put down to the absence of a corresponding activity mediated by the .alpha.2- receptors.
