Description

Foreliggende oppfinnelse er en videre utvikling av fremgangsmåten ifølge norsk patent 136.460 og angår en enkel og for-delaktig fremgangsmåte ved fremstilling av N-(1-ethyl-a-pyrroli-dylmethyl)-2-methoxy-5-sulfamidobenzamid, hvilket kan anvendes ved behandling av mave- og tarmsykdommer, såvel som innen psykia-trien. The present invention is a further development of the method according to Norwegian patent 136,460 and relates to a simple and advantageous method for the production of N-(1-ethyl-a-pyrrolidylmethyl)-2-methoxy-5-sulfamidobenzamide, which can be used in treatment of stomach and intestinal diseases, as well as in psychiatry.

Nærmere bestemt angår oppfinnelsen en fremgangsmåte ifølge norsk patent 136.460 ved fremstilling av N-[(1-ethylpyrro-lidinyl-2-)-methyl]-2-methoxy-5-sulfamoylbenzamid av formelen: ^VS°2NH2 More specifically, the invention relates to a method according to Norwegian patent 136,460 for the production of N-[(1-ethylpyrro-lidinyl-2-)-methyl]-2-methoxy-5-sulfamoylbenzamide of the formula: ^VS°2NH2

Fremgangsmåten forløper efter følgende reaksjohsskjerna: The procedure proceeds according to the following reaction core:

Den nye fremgangsmåte kan på en enkel måte gjennomfø-res praktisk slik det etterfølgende eksempel beskriver. The new method can be carried out in a simple way in practice, as the following example describes.

Et reaksjonskar på 1 liter ble utstyrt med en rører, termometer og kjøler, såvel som en dråpetrakt. I denne reak-sjonskolbe ble innført 27 g (0,21 mol) N-ethyl-o-aminomethyl-pyrrolidin og 560 ml pyridin. A 1 liter reaction vessel was equipped with a stirrer, thermometer and cooler, as well as a dropping funnel. 27 g (0.21 mol) of N-ethyl-o-aminomethyl-pyrrolidine and 560 ml of pyridine were introduced into this reaction flask.

I denne oppløsning ble dråpevis tilsatt ved en tempera-tur av 20°C en oppløsning av 6,1 g (0,04 mol) fosforoxyklorid i 65 ml pyridin. Innholdet ble omrørt en halv time, hvorefter 14,8 g (0,064 mol) 2-methoxy-5-sulfamidobenzoesyre ble tilført, og blandingen ble kokt 4 1/2 time ved tilbakeløpskjøling. A solution of 6.1 g (0.04 mol) phosphorus oxychloride in 65 ml pyridine was added dropwise to this solution at a temperature of 20°C. The contents were stirred for half an hour, after which 14.8 g (0.064 mol) of 2-methoxy-5-sulfamidobenzoic acid were added, and the mixture was refluxed for 4 1/2 hours.

Den erholdte reaksjonsblanding ble under redusert trykk inndampet til det halve volum, filtrert, og filtratet ble inndampet til tørrhet. Det gjenværende produkt ble oppløst i 200 ml vann og ved tilsetning av 40 ml saltsyre bragt til en pH på 1. The resulting reaction mixture was evaporated under reduced pressure to half the volume, filtered, and the filtrate was evaporated to dryness. The remaining product was dissolved in 200 ml of water and brought to a pH of 1 by adding 40 ml of hydrochloric acid.

Den filtrerte oppløsning fikk stå over natten i et kjø-leskap, ble derefter filtrert, og bunnfallet ble tørket i varmeskap ved 50°C. The filtered solution was allowed to stand overnight in a refrigerator, then filtered, and the precipitate was dried in a heating cabinet at 50°C.

Dette bunnfall ble oppløst i varmt vann. En mindre opp-løselig rest ble filtrert under kokning, hvorefter den varme opp-løsning ble gjort alkalisk med ammoniakk. This precipitate was dissolved in hot water. A less soluble residue was filtered while boiling, after which the hot solution was made alkaline with ammonia.

Oppløsningen ble avkjølt, filtrert, vasket med vann, og bunnfallet ble tørket i varmeskap ved 50°C. Der ble erholdt 7,5 g N-(1-ethyl-a-pyrrolidylmethyl)-2-methoxy-5-sulfamidobenzamid med smeltepunkt 179°C. The solution was cooled, filtered, washed with water, and the precipitate was dried in an oven at 50°C. 7.5 g of N-(1-ethyl-α-pyrrolidylmethyl)-2-methoxy-5-sulfamidobenzamide with a melting point of 179°C were obtained.

Analyse av nitrogeninnholdet ved hjelp av perklorsyre (100 %) ga en nitrogenverdi på 12,4 g (beregnet 12,32 %). Analysis of the nitrogen content using perchloric acid (100%) gave a nitrogen value of 12.4 g (calculated 12.32%).

Mellomproduktet N,N'N"-(1-ethyl-a-pyrrolidylmethyl)-fosforamid kan isoleres i form av en hygroskopisk blanding fra di-og triklorhydratet når omsetningen av N-ethyl-a-aminomethyl-pyrro-lidin med fosforoxyklorid utføres i dioxan som oppløsningsmiddel og reaksjonsmedium. The intermediate N,N'N"-(1-ethyl-α-pyrrolidylmethyl)-phosphoramide can be isolated in the form of a hygroscopic mixture from the di- and trichlorohydrate when the reaction of N-ethyl-α-aminomethyl-pyrrolidine with phosphorus oxychloride is carried out in dioxane as solvent and reaction medium.
