Description

Fremgangsmåte for fremstilling av l-metyl-4-(p-amino-bensoyl)-amino - piperidin. Process for the production of 1-methyl-4-(p-amino-benzoyl)-amino-piperidine.

Det har vist seg at det kan oppnås 1-metyl-4- (p-amino-bensoyl) -amino-piperi-din med formelen It has been found that 1-methyl-4-(p-amino-benzoyl)-amino-piperidine can be obtained with the formula

ved at nitrogruppen i l-metyl-4-(p-nitro-bensoyl)-aminopiperidin reduseres til aminogruppe ved hjelp av katalytisk aktivert in that the nitro group in l-methyl-4-(p-nitro-benzoyl)-aminopiperidine is reduced to an amino group by means of catalytically activated

vannstoff. water substance.

Fremgangsmåten kan eksempelvis ut-føres slik at det l-metyl-4-(p-nitro-bensoyl)-amino-piperidin som kan fremstilles slik som angitt i patent nr. 87 451, reduseres i alkoholisk oppløsning ved værelsestemperatur med vannstoff som er aktivi-sert katalytisk. The method can, for example, be carried out so that the 1-methyl-4-(p-nitro-benzoyl)-amino-piperidine, which can be prepared as stated in patent no. 87 451, is reduced in an alcoholic solution at room temperature with hydrogen which is active -sert catalytic.

Det l-metyl-4-(p-amino-bensoyl)-amino-piperidin som fremstilles i henhold til The 1-methyl-4-(p-amino-benzoyl)-amino-piperidine prepared according to

foreliggende oppfinnelse er en base som er the present invention is a base which is

krystallisert ved værelsestemperatur og som crystallized at room temperature and as

med syrer danner varige salter. with acids form permanent salts.

Sluttproduktet har terapeutisk verdi-fulle farmakodynamiske egenskaper. Det The end product has therapeutically valuable pharmacodynamic properties. The

gjør h jer tevirksomheten regelmessig og do h jer tea business regularly and

skal i terapien benyttes til å bekjempe must be used in the therapy to combat

hjertearrytmi, spesielt når denne opptrer cardiac arrhythmia, especially when this occurs

under operasjoner, f. eks. som sidevirkning during operations, e.g. as a side effect

av narkotika. of drugs.

Eksempel: Example:

En oppløsning av 32,0 g l-metyl-4- amino-piperidin i 250 cm<3> bensol blir ved værelsestemperatur dråpevis biandet med en oppløsning av 55.0 g p-nitro-bensoyl-klorid i 250 cm<8> bensol, og blandingen får stå i 12 timer. Blandingen blir rystet ut med 300 cm<8> 1,5-n saltsyre, og det vandige saltsure lag blandet med natronlut til fenolftalein-alkalisk reaksjon. Det utfeldte l-metyl-4-(p-nitro-bensoyl)-amino-pipe-ridin blir sudd bort og omkrystallisert fra en kokende blanding av aceton og etanol (7 : 3). Smp. 197-198°. Oppløsningen av 19,0 g l-metyl-4-(p-nitro-bensoyl)-amino-piperidin i 400 cm<8 >abs etanol og 50 cm'<1> 36 pst. saltsyre blir hydrert ved værelsestemperatur i nærvær av 40 g fuktig palladiumkull (tilsvarende 800 mg palladium-metall) i løpet av ca. iy2 time. Den oppløsning som filtreres av fra katalysatoren blir inndampet i vakuum ved 50°, og oppløsningen av resten i 400 cm<s> vann blir blandet med 3-n natronlut til fenolftalein-alkalisk reaksjon. Den ut-skilte base, l-metyl-4-(p-amino-bensoyl)-amino-piperidin, har etter omkrystallise-ring fra den 18-dobbelte mengde av en blanding av aceton og vann (1 : 1) et smel-tepunkt på 195—197. For å fremstille hydrokloridet dampes oppløsningen av den fri base i den ekviva-lente mengde l-n saltsyre inn i vakuum ved 50° til tørr tilstand, og oppløsningen av resten i den 40-dobbelte mengde abs. alko- hol blandes med den 30-dobbelte mengder eter, hvorved l-metyl-4- (p-amino-bensoyl) -amino-piperidin-hydroklorid skiller seg ut krystallinsk. Smp. 188—190°. A solution of 32.0 g of l-methyl-4- amino-piperidine in 250 cm<3> benzene remains room temperature is mixed dropwise with a solution of 55.0 g of p-nitro-benzoyl chloride in 250 cm<8> of benzene, and the mixture is allowed to stand for 12 hours. The mixture is shaken out with 300 cm<8> of 1.5-n hydrochloric acid, and the aqueous hydrochloric acid layer is mixed with caustic soda for a phenolphthalein-alkaline reaction. It precipitated 1-methyl-4-(p-nitro-benzoyl)-amino-piperidine is washed away and recrystallized from a boiling mixture of acetone and ethanol (7:3). Temp. 197-198°. The solution of 19.0 g of 1-methyl-4-(p-nitro-benzoyl)-amino-piperidine in 400 cm<8 >abs ethanol and 50 cm'<1> 36% hydrochloric acid is hydrated at room temperature in the presence of 40 g moist palladium charcoal (equivalent to 800 mg palladium metal) during approx. iy2 hours. The solution filtered off from the catalyst is evaporated in vacuo at 50°, and the solution of the residue in 400 cm<s> of water is mixed with 3-n caustic soda for a phenolphthalein-alkaline reaction. The precipitated base, 1-methyl-4-(p-amino-benzoyl)-amino-piperidine, after recrystallization from the 18-fold amount of a mixture of acetone and water (1:1) has a melting tea point of 195-197. To prepare the hydrochloride, the solution of the free base in the equivalent amount of 1-n hydrochloric acid is evaporated in vacuo at 50° to a dry state, and the solution of the residue in the 40-fold amount of abs. alcohol hol is mixed with the 30-fold amount of ether, whereby 1-methyl-4-(p-amino-benzoyl)-amino-piperidine hydrochloride separates out crystalline. Temp. 188-190°.
