The latter compound which can be obtained by hydration of the above-mentioned new starting material is known for its therapeutic properties and is used in therapy against angina pectoris and disturbances of the heart rhythm.

Fra forbindelsen V kommer man til sluttproduktet I, f.eks. ved hjelp av katalytisk hydrering. En egnet katalysa-tor er palladium, hvorved bæreren kan være f.eks. aktivkull, aluminiumoksyd, bariumsulfat. Som oppløsningsmiddel kan anvendes lavere alkoholer, til hvilket det eventuelt er tilsatt mineralsyrer, iseddik eller blandinger derav. Alt etter opp-løsningsmidlet er den hensiktsmessige temperatur mellom romtemperatur og 80°C ogtrykket mellom 1 og 5 atmosfærer. Ved valget av oppøsningsmidlet, temperaturen, trykket samt katalysatoren og mengden derav ledes reaksjonen slik at hydroksygruppen i forbindelse V hydreres til en mety le.ngruppe . From the compound V you get to the final product I, e.g. by means of catalytic hydrogenation. A suitable catalyst is palladium, whereby the carrier can be e.g. activated carbon, aluminum oxide, barium sulfate. As a solvent, lower alcohols can be used, to which mineral acids, glacial acetic acid or mixtures thereof have optionally been added. Depending on the solvent, the appropriate temperature is between room temperature and 80°C and the pressure between 1 and 5 atmospheres. By choosing the dissolving agent, the temperature, the pressure as well as the catalyst and the amount thereof, the reaction is directed so that the hydroxy group in compound V is hydrogenated to a methylene group.

Fremstillingen av nevnte forbindelse er tidligere beskrevet, blant annet i NO-PS 132798.'I denne fremgangsmåte kreves det i fremstillingen av utgangsstoffet flere trinn, og en del av disse trinn har dårlig utbytte. The preparation of said compound has previously been described, among other things in NO-PS 132798. In this method, several steps are required in the preparation of the starting material, and some of these steps have a poor yield.

Utgangsmaterialet for fremstilling av forbindelsen V oppnås ,fra p-(1,l-dietoksy-2-ketoksyetyl)fenol eller et annet ketalderivet ifølge i litteraturen angitte fremgangsmåter,, The starting material for the preparation of compound V is obtained from p-(1,1-diethoxy-2-ketoxyethyl)phenol or another ketal derivative according to methods specified in the literature.

Man lar ketalderivatet: reagere med epiklorhydrin, hvorved det oppnås en forbindelse med formelen: The ketal derivative: is allowed to react with epichlorohydrin, whereby a compound with the formula is obtained:

Forbindelsen III amineres i isopropylamin, hvoretter ketalet nedbrytes i sur vannoppløsning, hvorved det oppnås en forbindelse med følgende formel: The compound III is aminated in isopropylamine, after which the ketal is decomposed in acidic water solution, whereby a compound with the following formula is obtained:

Fra forbindelsen II kommer man frem til forbindelsen IV uten rensning av mellomproduktene, hvorved fremstillingen kan utføres som en kontinuerlig prosess. From compound II one arrives at compound IV without purification of the intermediate products, whereby the preparation can be carried out as a continuous process.

Heretter underkastes forbindelsen IV en katalytisk hydroring som fører til oppnåelse av den tilsvarende hydroksy-forbindel^e med formelen: The compound IV is then subjected to a catalytic hydrogenation which leads to obtaining the corresponding hydroxy compound with the formula:

Følgende eksempler skal illustrere oppfinnelsen nærmere uten å innskrenke beskyttelsesomfanget Eks empel 1 The following examples shall illustrate the invention in more detail without limiting the scope of protection Example 1

l-isop ropylamin-5-[ p-(2- metoksy-l-ok syet yl) fenoksyj - 2- propanol 1-isopropylamine-5-[p-(2-methoxy-1-oxyethyl)phenoxy-2-propanol

Man fremstiller en natriummetanolatoppløsning med A sodium methanolate solution is prepared with

'4,4 g natrium og 270 ml etanol. Til den oppnådde oppløsning tilsettes ved romtemperatur 37,7 g p-(1,l-dietoksy-2-metoksyetyl)fenol. Man tilsetter 55 ml epiklorhydrin og blander ved romtemperatur i 1 døgn. Deretter dampes det hele inn. '4.4 g of sodium and 270 ml of ethanol. To the solution obtained, 37.7 g of p-(1,1-diethoxy-2-methoxyethyl)phenol are added at room temperature. 55 ml of epichlorohydrin is added and mixed at room temperature for 1 day. The whole thing is then steamed in.

Resten opptas i kloroform og vaskes med vann. Deretter følger tørking med natriumsulfat og inndamping. Inndampingsresten oppløses i 300 ml isopropylamin, og oppløsningen kokes under tilbakeløp i 1 døgn og deretter dampes det hele inn igjen. Inndampingsresten oppløses i vann, og oppløsningens pH juster-es til 1 ved hjelp av saltsyre. Por fullstendig nedbryting av ketalet, blandes det 1 time ved romtemperatur. Deretter følger en vaskeekstraksjon med etylacetat. Vannfasen gjøres basisk med konsentrert ammoniakk, og produktet ekstraheres med etylacetat. Ekstraktene behandles med aktivkull, tørkes og dampes inn. Produktet krystalliseres som hydroklorid ved opp-løsning i HCl-isopropanol og utfelling med etylacetat. Det oppnådde hydroklorid har et smeltepunkt på 125-126°C. The residue is taken up in chloroform and washed with water. This is followed by drying with sodium sulphate and evaporation. The evaporation residue is dissolved in 300 ml of isopropylamine, and the solution is boiled under reflux for 1 day and then the whole is evaporated again. The evaporation residue is dissolved in water, and the pH of the solution is adjusted to 1 using hydrochloric acid. For complete decomposition of the ketal, it is mixed for 1 hour at room temperature. This is followed by a washing extraction with ethyl acetate. The water phase is made basic with concentrated ammonia, and the product is extracted with ethyl acetate. The extracts are treated with activated carbon, dried and evaporated. The product is crystallized as hydrochloride by dissolution in HCl-isopropanol and precipitation with ethyl acetate. The resulting hydrochloride has a melting point of 125-126°C.

Således oppnådd 10 g l-isopropylamin-3-/p-(2-metoksy-1-oksoetyl)-fenoksyj-2-propanolhydroklorid oppløses i 150 ml eddiksyre. Deretter tilsettes 1,5 g 10%-ig palladiumkull, og man gjennomfører en hydrering ved 30-40°C og normaltrykk inntil en ekvivalent hydrogen er forbrukt. Deretter filtreres katalysatoren av, og oppløsningsmidlet avdampes. Resten oppløses i vann, og oppløsningen gjøres alkalisk med lut. Produktet oppløses i kloroform. Kloroformen dampes :.av. Tartratet frem-stilles av produktet i vinsurt aceton. Det oppnådde tartrat har i krystallisert form et smeltepunkt på ca. 120°C. The thus obtained 10 g of 1-isopropylamine-3-(p-(2-methoxy-1-oxoethyl)-phenoxy-2-propanol hydrochloride) is dissolved in 150 ml of acetic acid. Then 1.5 g of 10% palladium charcoal is added, and a hydration is carried out at 30-40°C and normal pressure until an equivalent of hydrogen has been consumed. The catalyst is then filtered off, and the solvent is evaporated. The remainder is dissolved in water, and the solution is made alkaline with lye. The product is dissolved in chloroform. The chloroform is evaporated :.off. The tartrate is produced from the product in tartaric acetone. In crystallized form, the obtained tartrate has a melting point of approx. 120°C.
