Description
Fremgangsmåte for fremstilling av terapeutisk aktive azabicyklo-(3,2,l)-oktaner og -oktener. Process for the production of therapeutically active azabicyclo-(3,2,1)-octanes and -octenes.
Nærværende oppfinnelse angår en fremgangsmåte for fremstilling av terapeutisk aktive stoffer. The present invention relates to a method for the production of therapeutically active substances.
Ifølge nærværende oppfinnelse frem- According to the present invention,
skaffes der aza-bicyklo-(3,2,1)-oktaner og aza-bicyclo-(3,2,1)-octanes and
-oktener overensstemmende med den ene eller den annen av de planare generelle formler I og II. -octenes corresponding to one or the other of the planar general formulas I and II.
i hvilke X og Y hver betyr et vannstoffatom eller sammen betyr en enkel binding, R,, R2 og R4 hver betyr et vannstoffatom eller en lavere alkylgruppe, f. eks. en metyl-eller etyl-gruppe, og R:i betyr en lavere alkylgruppe, og sure addisjons- eller kvaternære salter av denne. Ved uttrykket «lavere alkyl» forståes en alkylgruppe inneholdende ikke mere enn seks og fortrinnsvis ikke mere enn fire kullstoffatomer. in which X and Y each represent a hydrogen atom or together represent a single bond, R 1 , R 2 and R 4 each represent a hydrogen atom or a lower alkyl group, e.g. a methyl or ethyl group, and R:i means a lower alkyl group, and acid addition or quaternary salts thereof. The term "lower alkyl" means an alkyl group containing no more than six and preferably no more than four carbon atoms.
Etter oppfinnelsen foretrukne forbindelser er dem i hvilke X og Y betyr vannstoffatomer, R;i betyr en metylgruppe, og ikke mere enn en av Ri, R2 og R4 betyr et vanstoffatom, og de øvrige betyr metyl-grupper. Preferred compounds according to the invention are those in which X and Y mean hydrogen atoms, R;i means a methyl group, and no more than one of Ri, R 2 and R 4 means a hydrogen atom, and the others mean methyl groups.
Forbindelsene etter formel I og II, f.eks. 2-aza-3:4:4-trimetyl-bicyklo-(3,2,1)-oktan, 2-aza-2:3:4:4-tetrametyl-bicyklo-(3,2,1)-oktan, 3-aza-2:4:4-trimetyl-bicyklo-(3,2,l)-oktan, og 3-aza-2:3:4:4-tetrametyl-bicyklo-( 3,2,1)-oktan er i besiddelse av terapeutisk aktivitet og er f. eks. kraftige ganglion blokerende midler. The compounds of formula I and II, e.g. 2-aza-3:4:4-trimethyl-bicyclo-(3,2,1)-octane, 2-aza-2:3:4:4-tetramethyl-bicyclo-(3,2,1)-octane, 3-aza-2:4:4-trimethyl-bicyclo-(3,2,1)-octane, and 3-aza-2:3:4:4-tetramethyl-bicyclo-(3,2,1)-octane has therapeutic activity and is e.g. powerful ganglionic blocking agents.
Ifølge oppfinnelsen kan forbindelsene etter formel I og II fremstilles ved å be-handle en forbindelse med den generelle formel III med litiumaluminiumhydrid: According to the invention, the compounds of formulas I and II can be prepared by treating a compound of the general formula III with lithium aluminum hydride:
i hvilken formel X, Y, Ri, R2 og Rn er som foran definert (etter først å ha hvis ønsket, redusert etylen-dobbeltbindingen etter kjente metoder, f. eks. ved katalytisk hydrering i nærvær av et edelt metall kata-lysator), og når Rt skal bety en lavere alkylgruppe alkylering av det sekundære amin slik fremstilt. Forløpet av foregående reaksjon med litiumaluminiumhydrid, som omfatter en strukturell omforandring i form av ringekspansjon ved hvilken det oksocykliske kvelstoffatom i nitrogruppen blir del i ringstrukturen, er fullstendig uventet. Analogt med reduksjon av nitrogruppen i forbindelse med formel III ved hjelp av jern og saltsyre eller ved katalytisk hydrering skulle reaksjonen med litiumaluminiumhydrid ha resultert i blott og bar ombyttning av nitrogruppen med en pri-mær aminogruppe. in which formula X, Y, Ri, R2 and Rn are as defined above (after first having, if desired, reduced the ethylene double bond by known methods, e.g. by catalytic hydrogenation in the presence of a noble metal catalyst), and when Rt is to mean a lower alkyl group alkylation of the secondary amine thus prepared. The course of the preceding reaction with lithium aluminum hydride, which includes a structural change in the form of ring expansion whereby the oxocyclic nitrogen atom in the nitro group becomes part of the ring structure, is completely unexpected. Analogous to the reduction of the nitro group in connection with formula III by means of iron and hydrochloric acid or by catalytic hydrogenation, the reaction with lithium aluminum hydride should have resulted in the mere exchange of the nitro group with a primary amino group.
Reaksjonen utføres fortrinnsvis i et inert oppløsningsmiddel som dietyleter. Den gir en blanding av isomerer som kan separeres etter standardmetoder som det vil bli illustrert i de følgende eksempler, men som kan isoleres som sådanne, og disse blandinger er naturligvis terapautisk anvendelige og egnet for direkte farmasøy-tisk anvendelse i form av standardprepa-rater. The reaction is preferably carried out in an inert solvent such as diethyl ether. It gives a mixture of isomers which can be separated by standard methods as will be illustrated in the following examples, but which can be isolated as such, and these mixtures are of course therapeutically applicable and suitable for direct pharmaceutical use in the form of standard preparations.
Mellomproduktene etter formel III i hvilken X og Y sammen betyr en enkel binding, og Ri, R?, og R.i har den betydning som foran angitt, kan fremstilles ved Diels-Adler kondensasjon av cyklo-pentadien og det egnete nitroalken med formelen Ri (R2) C = C (R;i) NO2 på en måte liknende den beskrevet av Noland og Banbury (J. Amer. Chem. Soc. 1955, 77, 6386). Mellomproduktene etter generell formel III i hvilken X og Y er vannstoffatomer og Ri = R2 = R:1 =CH:i, kan fremstilles fra i han-delen tilgjengelig d-kamfen etter Hiickel og Nerdels metode (Ann. 528, 57, 1937). The intermediates according to formula III in which X and Y together mean a single bond, and Ri, R?, and R.i have the meaning as indicated above, can be prepared by Diels-Adler condensation of cyclopentadiene and the suitable nitroalk with the formula Ri (R2 ) C = C (R;i) NO2 in a manner similar to that described by Noland and Banbury (J. Amer. Chem. Soc. 1955, 77, 6386). The intermediates according to general formula III in which X and Y are hydrogen atoms and Ri = R2 = R:1 =CH:i, can be prepared from d-camphene available in the male part according to Hiickel and Nerdel's method (Ann. 528, 57, 1937) .
De bicykliske forbindelser etter formel The bicyclic compounds by formula
I og II kan eksistere i geometriske og op-tiske isomere former, og alle slike former og blandinger og rasemater av disse faller innenfor oppfinnelsens område. Disse forbindelser er av betraktelig betydning på grunn av de hypotensive egenskaper de har vist seg å være i besiddelse av, og disse egenskaper er karakteristiske ikke bare for de enkelte isomerer, men også naturligvis for blandinger av disse. For terapeutiske formål kan de administreres på vanlig måte for ganglion blokerende midler, dvs. subkutant eller oralt. Basene etter formel I og II brukes fortrinnsvis i form av salter inneholdende farmasøytisk aksepterbare anioner. Egnete sure addisjonssalter omfatter hydrokloridene og andre hydro-halogenider, fosfater, nitrater, sulfater, maleater, fumarater, sitrater, tartrater, oksalater, mentansulfonater, og etandisul-fonater. Egnete kvaternære ammonium-forbindelser omfatter metohalogenider og de tilsvarende metylsulfater og tartrater. I and II can exist in geometric and optical isomeric forms, and all such forms and mixtures and racemates of these fall within the scope of the invention. These compounds are of considerable importance because of the hypotensive properties they have been shown to possess, and these properties are characteristic not only of the individual isomers, but also of course of mixtures thereof. For therapeutic purposes, they can be administered in the usual way for ganglion blocking agents, i.e. subcutaneously or orally. The bases according to formulas I and II are preferably used in the form of salts containing pharmaceutically acceptable anions. Suitable acid addition salts include the hydrochlorides and other hydrohalides, phosphates, nitrates, sulfates, maleates, fumarates, citrates, tartrates, oxalates, methanesulfonates, and ethanedisulfonates. Suitable quaternary ammonium compounds include metho halides and the corresponding methyl sulfates and tartrates.

Diels-Alder adduktet 5:6-dimetyl-6-ni-trobicyklo-(2,2,1 )-2-hepten (16.7 g), fremstillet etter Noland og Banbury's metode (J.A.C.S. 1955, 77, 6386), hydrertes ved ryst-ning i et rustfri stålkar ved 2.1 kg/cm'-trykk under bruk av 0.75 % platinaoksyd-katalysator i iseddikk (94 ml.) ved en mak-simal temperatur på 27° C. Absorpsjon av vanstoff opphørte etter 30 minutter da 100 % av den teoretiske mengde vannstoff var blitt absorbert. Etter filtrering ble ed-dikksyren fjernet i vacuum og residuet (15.66 g.) oppløst i eter (100 ml) og vasket med vann. Eterlaget ble tørret over magnesiumsulfat. Suspensjonen ble filtrert og eteren fjernet i vacuum og ga et vokslik-nende fast stoff. Dette faste stoff ble destillert i vakuum og gir 5:6-dimetyl-6-nitro-bicyklo-(2,2,1 )-heptan som et svakt gult fast stoff (15.32 g.), smeltepunkt 67—74° C. The Diels-Alder adduct 5:6-dimethyl-6-nitrobicyclo-(2,2,1 )-2-heptene (16.7 g), prepared by Noland and Banbury's method (J.A.C.S. 1955, 77, 6386), was hydrated by shaking in a stainless steel vessel at 2.1 kg/cm' pressure using 0.75% platinum oxide catalyst in glacial acetic acid (94 ml.) at a maximum temperature of 27° C. Absorption of water ceased after 30 minutes when 100% of the theoretical amount of hydrogen had been absorbed. After filtration, the acetic acid was removed in vacuo and the residue (15.66 g.) dissolved in ether (100 ml) and washed with water. The ether layer was dried over magnesium sulfate. The suspension was filtered and the ether removed in vacuo to give a wax-like solid. This solid was distilled in vacuo to give 5:6-dimethyl-6-nitro-bicyclo-(2,2,1)-heptane as a faint yellow solid (15.32 g.), melting point 67-74°C.
5:6-dimetyl-6-nitro-bicyklo- (2,2,1) - heptan (14.5 g.) i eter (50 ml.) ble i løpet av 38 minutter tilsatt til litiumaluminiumhydrid (9.8 g.) i eter (150 ml.). Suspensjonen ble omrørt ved romtemperatur i ytterligere 21 timer. Vannmettet eter (50 ml.), derpå vann (25 ml.) og endelig 20 vektsprosent natriumhydroksyd (50 ml.) ble tilsatt til suspensjonen. Etter filtrering ble eterlaget ekstrahert med 2n saltsyre (4 x 30 ml.). Syrelaget ble gjort alkalisk med 50 vektsprosent natriumhydroksyd. Den frigjorte base ble ekstrahert i eter (4 x 25 ml.) 5:6-dimethyl-6-nitro-bicyclo-(2,2,1)-heptane (14.5 g.) in ether (50 ml.) was added over 38 minutes to lithium aluminum hydride (9.8 g.) in ether ( 150 ml.). The suspension was stirred at room temperature for an additional 21 hours. Aqueous ether (50 ml.), then water (25 ml.) and finally 20% by weight sodium hydroxide (50 ml.) were added to the suspension. After filtration, the ether layer was extracted with 2N hydrochloric acid (4 x 30 ml.). The acid layer was made alkaline with 50% by weight sodium hydroxide. The liberated base was extracted into ether (4 x 25 ml.)
og tørret over magnesiumsulfat. Suspensjonen ble filtrert og eteren fjernet i vacuum og ga 10.53 g av en fargeløs basisk olje. Denne olje (10,48 g) ble oppløst i tørr benzol og oppvarmet under tilbakeløp i et Dean og Stark apparat med et overskudd av benzaldehyd. Det ble ikke iaktatt at vann de-stillerer ut. Benzoloppløsningen ble iskjølt og ekstrahert med iskald 2n eddikksyre (4 x 20 ml.). Det sure lag ble gjort alkalisk med 50 vektsprosent natriumhydroksyd. Den frigjorte base ble ekstrahert med eter (4 x 50 ml.) og tørret over magnesiumsulfat. Suspensjonen ble filtret og eteren fjernet i vacuum og gir 9.7 g av en fargeløs base. En del av denne sekundære base ble destillert for å gi et amin som har strukturen 2(eller 3)-aza-3(eller 2) :4-dimetyl-bicyklo-(3,2,1)-oktan, kokepunkt ca. 75° C ved 10 mm. Denne forbindelse har det in-fra-røde absorpsjonsspektrum som vises i fig. 1 og oppviser karakteristiske absorp-sjonsband ved følgende bølgelengder uttrykt i mikroner (toleranse ± 0,02 mikroner): 3.06, 3.44, 3.52, 3.62, 3.78, 3.87, 6.89, 7.05, 7.31, 7.42, 7.50, 7.58, 7.66, 7.72, 7.82, 7.91, 8.17, 8.24, 8.35, 8.48, 8.53, 8.65, 8.94, 9.03, 9.06. 9.13, 9.36, 9.48, 9.59, 9.88, 9.95, 10,32, 10,35, 10.45, 10.55, 10.68, 10.97, 11.02, 11.40, 11.56, 11.90, 12.71, 12.96, 13.25, 13.78, 14.00, 14.68, 14.85. and dried over magnesium sulfate. The suspension was filtered and the ether removed in vacuo to give 10.53 g of a colorless basic oil. This oil (10.48 g) was dissolved in dry benzene and heated under reflux in a Dean and Stark apparatus with an excess of benzaldehyde. It was not observed that water distils out. The benzene solution was ice-cooled and extracted with ice-cold 2N acetic acid (4 x 20 ml.). The acid layer was made alkaline with 50% by weight sodium hydroxide. The liberated base was extracted with ether (4 x 50 ml.) and dried over magnesium sulfate. The suspension was filtered and the ether removed in vacuo to give 9.7 g of a colorless base. A portion of this secondary base was distilled to give an amine having the structure 2(or 3)-aza-3(or 2):4-dimethyl-bicyclo-(3,2,1)-octane, bp ca. 75° C at 10 mm. This compound has the infrared absorption spectrum shown in fig. 1 and exhibits characteristic absorption bands at the following wavelengths expressed in microns (tolerance ± 0.02 microns): 3.06, 3.44, 3.52, 3.62, 3.78, 3.87, 6.89, 7.05, 7.31, 7.42, 7.50, 7.58, 7.66, 7.72, 7.82, 7.91, 8.17, 8.24, 8.35, 8.48, 8.53, 8.65, 8.94, 9.03, 9.06. 9.13, 9.36, 9.48, 9.59, 9.88, 9.95, 10.32, 10.35, 10.45, 10.55, 10.68, 10.97, 11.02, 11.40, 11.56, 11.56, 11.90, 12.71, 12.71, 13.96, 13.25, 13.78, 14.7, 14.7, 14.7, 14.7, 14.7..
Dette sekundære amin (1 g) ble tilsatt ved under 30° C til 90 % maursyre (0.87 g). Blandingen ble oppvarmet til 65— 70° C og 40 % formaldehyd (0.78 g) tilsatt. Reaksjonsblandingen ble opphetet ved 95—100°C i ytterligere 22 timer. Saltsyre 2n (5 ml) ble tilsatt, og oppløsningen ble fordampet i vakuum og ga et svakt brunt-viskøst residuum. Mettet kaliumjodidopp-løsning (15 ml) ble tilsatt til en konsentrert vandig oppløsning av dette residuum, og et kremliknende fast stoff (1.78 g) krystali-serte ut. Dette faste stoff ble omkrystallisert fra tørr isopropanol og gir et salt som har strukturen 2(eller 3)- aza-2:3:4-trime-tyl-bicyklo-(3,2,1)-oktan hydrojodid, smeltepunkt 236—238° C. This secondary amine (1 g) was added at below 30° C. to 90% formic acid (0.87 g). The mixture was heated to 65-70° C and 40% formaldehyde (0.78 g) added. The reaction mixture was heated at 95-100°C for a further 22 hours. Hydrochloric acid 2n (5 mL) was added and the solution was evaporated in vacuo to give a slightly brown viscous residue. Saturated potassium iodide solution (15 ml) was added to a concentrated aqueous solution of this residue, and a cream-like solid (1.78 g) crystallized. This solid was recrystallized from dry isopropanol to give a salt having the structure 2(or 3)-aza-2:3:4-trimethyl-bicyclo-(3,2,1)-octane hydroiodide, mp 236-238 °C.

Saltsyre (10n:19.8 ml.) ble tilsatt, og oppløsningen ble fordampet i vakuum og ga en hvitaktig fast masse. Denne faste masse ble oppløst i vann og behandlet med sterk natriumhydroksyd. Den bunnfelte base ble ekstrahert i eter og tørret over natriumsulfat. Etter filtrering ble den eteriske oppløsning behandlet med tørr eterisk bromvannstoff. Det bunnfelte faste stoff ble filtrert, vasket med eter og tørret over kaliumhydroksyd. Det rå hydrobromid ble omkrystallisert fra tørr etanol/eter og tørret ved 42° C, og gir 30 g av en blanding av hydrobromidene av to isomere baser representert ved de planare strukturer 2-aza-2:3:4:4-tetrametyl-bicyklo- (3,2,1) -oktan og/eller 3-aza-2:3:4:4-tetrametyl-bicyklo-(3,2,1)-oktan.

The mixture was heated to 65-70° C, and 40% formaldehyde (21.5 g) was added. The reaction mixture was heated at 95-100° C. for 21 hours. Hydrochloric acid (10n:19.8 ml.) was added and the solution was evaporated in vacuo to give a whitish solid. This solid mass was dissolved in water and treated with strong sodium hydroxide. The precipitated base was extracted into ether and dried over sodium sulfate. After filtration, the ethereal solution was treated with dry ethereal hydrogen bromide. The precipitated solid was filtered, washed with ether and dried over potassium hydroxide. The crude hydrobromide was recrystallized from dry ethanol/ether and dried at 42°C, yielding 30 g of a mixture of the hydrobromides of two isomeric bases represented by the planar structures 2-aza-2:3:4:4-tetramethyl-bicyclo - (3,2,1)-octane and/or 3-aza-2:3:4:4-tetramethyl-bicyclo-(3,2,1)-octane.

20 d-kamfen (420 g), [a] ^ = +21.30° (c = 5, alkohol), i petroleter (450 cm<3>) met-tes i løpet av iy2 time med tørt klorvannstoff under omrøring og kjøling til -f- 40° C. Petroleter og overskuddet av klorvannstoff fjernes derpå i vakuum ved en lav temperatur, og d-kamfenhydrokloridet slik oppnådd tørres i vakuum i nærvær av kaliumhydroksyd. Der oppnås 515 g, smeltepunkt 163° C (Kofler). d-kamfenhydroklorid (415 g) oppløses i vannfri eter (3 1), sølvnitrit (380 g) tilsettes derpå i små porsjoner til den oppnådde oppløsning mens temperaturen holdes ved + 3° C, og omrøringen fortsettes i 24 timer hvorunder temperaturen holdes ved ca. + 3° C. Det dannete sølvklorid skil-les fra, og den eteriske oppløsning av 3-nitro-isokamfan slik oppnådd brukes direkte for det følgende trinn. 20 d-camphene (420 g), [a] ^ = +21.30° (c = 5, alcohol), in petroleum ether (450 cm<3>) is saturated in the course of 1y2 hours with dry hydrogen chloride while stirring and cooling to -f- 40° C. Petroleum ether and the excess of hydrogen chloride are then removed in vacuo at a low temperature, and the d-camphene hydrochloride thus obtained is dried in vacuo in the presence of potassium hydroxide. 515 g is obtained, melting point 163° C (Kofler). d-camphene hydrochloride (415 g) is dissolved in anhydrous ether (3 1), silver nitrite (380 g) is then added in small portions to the solution obtained while the temperature is maintained at + 3° C, and stirring is continued for 24 hours during which the temperature is maintained at approx. . + 3° C. The silver chloride formed is separated, and the ethereal solution of 3-nitro-isocamphane thus obtained is used directly for the following step.
Denne oppløsning tilsettes gradvis under opprettholdelse av et passende tilbake-løp til en omrøret blanding av litiumaluminiumhydrid (171 g) og eter (4 1.). Omrør-ingen fortsettes over natt, og blandingen behandles derpå med vann (160 cm<3>) og 15% vandig natriumhydroksyd (160 cm:i), fulgt av vann (500 cm<3>). Det dannete bunnfall filtreres fra og vaskes med eter. De forenete eteriske oppløsninger sur gjøres med normal saltsyre (385 cm3) og ekstraheres med vann (400 cm:0- This solution is added gradually while maintaining a suitable reflux to a stirred mixture of lithium aluminum hydride (171 g) and ether (4 L). Stirring is continued overnight, and the mixture is then treated with water (160 cm<3>) and 15% aqueous sodium hydroxide (160 cm:i), followed by water (500 cm<3>). The precipitate formed is filtered off and washed with ether. The combined ethereal solutions are acidified with normal hydrochloric acid (385 cm3) and extracted with water (400 cm:0-
Den således oppnådde vandige oppløs-ning behandles med litiumpikrat, og der oppnås slik, etter omkrystallisering fra vandig alkohol, et pikrat (93 g), smeltepunkt 199° C (Kofler). The aqueous solution thus obtained is treated with lithium picrate, and there is thus obtained, after recrystallization from aqueous alcohol, a picrate (93 g), melting point 199° C (Kofler).
Dette pikrat omdannes til den tilsvarende base (35 g), basen oppløses i benzol (100 cm<3>), og benzaldehyd (24.2 g) tilsettes. Blandingen oppvarmes i 3 timer ved 100° C og benzolen og vann fjernes derpå ved destillasjon under normalt trykk og derpå i vakuum. This picrate is converted to the corresponding base (35 g), the base is dissolved in benzene (100 cm<3>), and benzaldehyde (24.2 g) is added. The mixture is heated for 3 hours at 100° C. and the benzene and water are then removed by distillation under normal pressure and then in vacuum.
Metylsulfat (28,8 g) tilsettes forsiktig til den slik oppnådde base. Reaksjonen er kraftig og fullendes ved oppvarmning i 3 timer ved 100° C. Methyl sulfate (28.8 g) is carefully added to the base thus obtained. The reaction is vigorous and is completed by heating for 3 hours at 100° C.
Til det oppnådde produkt tilsettes alkohol (200 cm<3>), fulgt av vann (100 cm3), og blandingen oppvarmes i 3 timer under til-bakeløp. Alkoholen drives av, og den vandige oppløsning ekstraheres med eter (3 x 50 cm<3>) og gjøres alkalisk. Basen som skiller seg fra ekstraheres med eter, den eteriske ekstrakt tørres, og eteren fjernes i vakuum. Der oppnås på denne måte en blanding av baser (27,7 g) som oppløses i aceton (200 cm3), og, etter tilsetning av den teoretiske mengde av eterisk klorvannstoff, bunnfelles hydrokloridet av et produkt A, smeltepunkt = 315—320° C, hvilket produkt er relativt uoppløselig i aceton. Behandling av acetonmoderluten med en mettet acetonoppløsning av pikrin-syre, fulgt av omkrystallisering av bunnfal-let fra 30 % etanol (600 cm<3>) gir 18 g av et pikrat, smeltepunkt 275—276° C. Etter omdanning til hydrokloridet og omkrystal-lisasjon fra metyletylketon (25 cm<3>), oppnås der hydrokloridet av et produkt B (3 g), smeltepunkt 252—255° C.

To the product obtained is added alcohol (200 cm<3>), followed by water (100 cm3), and the mixture is heated for 3 hours under reflux. The alcohol is driven off, and the aqueous solution is extracted with ether (3 x 50 cm<3>) and made alkaline. The base which separates is extracted with ether, the ethereal extract is dried, and the ether is removed in vacuo. A mixture of bases (27.7 g) is obtained in this way, which is dissolved in acetone (200 cm3), and, after the addition of the theoretical amount of ethereal hydrogen chloride, the hydrochloride of a product A, melting point = 315-320° C, precipitates , which product is relatively insoluble in acetone. Treatment of the acetone mother liquor with a saturated acetone solution of picric acid, followed by recrystallization of the precipitate from 30% ethanol (600 cm<3>) gives 18 g of a picrate, melting point 275-276° C. After conversion to the hydrochloride and recrystallization -lysis from methyl ethyl ketone (25 cm<3>), is obtained where the hydrochloride of a product B (3 g), melting point 252-255° C.
