Description

Przedmiotem wynalazku jest sposób wytwarza¬ nia N-(dwuetyloaminoetylo)-2-metoksy-5-metylo- sulfonylobenzamidu o wzorze 3 i jego farmakolo¬ gicznie dopuszczalnych soli z kwasami nieorgani- czynymi i organicznymi oraz jego czwartorzedo¬ wych soli amoniowych, na drodze reakcji kwasu 2-metoksy-5-meitylosulfonylobenzoesowago o wzo- - rze 1, rozpuszczonego w rozpuszczalniku, zN,N',N/r- trlis- rze 2, wedlug schematu 1.Stosowany jako substcrat N,N',N"-tris-(dwuetylo- amdinoetylo)- fosforamiid o wrzoirze 2 otrzymuje sie sie na drodze reakcji tlenochlotrku fosforu z dwu- etyloaminoetyloamina wedlug schematu 2.Omówione znane reakcje prowadzi sie w obo¬ jetnych rozpuszczalnikach, przy czym najpierw wytraca sie zawsze ^hldrowodiorek fosforaniidu o wzorze 2, który oddziela sie i przeprowadza w zasade, a doipiero pózniej poddaje ja dalszej obróbce i reakcji z kwasem benzoesowym o wzo¬ rze 1.Kazdorazowe wyodrebnienie i oczyszczanie fo- sforoamidu o wzorze 2, stanowiacego oleista, le¬ pka substancje, trudna w obróbce, a zwlaszcza w oczyszczaniu, jest uciazliwe.Celem wynalazku jest wyeliminowanie omówio¬ nej niedogodnosci. W tym celu nalezy rozwiazac zagadnienie takiego prowadzenia sposobu, poprzez dobór odpowiedniego rozpuszczalnika, aby zbe¬ dnym stalo sie wyodrebnianie i Oczyszczanie f0- JO sforamidu przed wprowadzeniem go do reakcji "w sposobie wedlug wynalazku.Cel ten osiaga sie w sposobie wedlug wynalazku, polegajacym na tym, ze jako rozpuszczalnik w reakcji kwasu 2-metoksy-5-metylobenzoesowego o wzorze 1 z N,N',N,,-tris-l(dwuetyloaminoetylo)- -fosforamidem o wzorze 2 stosuje sie pirydyne.Stosowanie pirydyny równiez i w reakcji aminy z tlenochlorkiem fosforu (wedlug schematu 2) ma i]* zalete, ze pirydyna wiaze powstajacy kwas sol¬ ny a jednoczesnie rozpuszcza wolny, oleisty fosfo- ramid o wzorze 2, umozliwiajac tym samym dal¬ sza bezposrednia reakcje z kwasem benzoesowym o wzorze 1, wedlug schematu 1, w jednym ciagu i w jednym naczyniu reakcyjnym.Przy zastosowaniu pirydyny jako rozpuszcza¬ lnika jest wiec uprzednie wyodrebnianie i oczy¬ szczanie chlorowodorku fdsforamidu o wzorze 2 oraz jego przeksztalcanie w zasade zbedne. Dzieki zastosowaniu pirydyny jako rozpuszczalnika eli¬ minuje sie zatem co najmniej dwa zabiegi ope¬ racyjne, niezbedne w dotychczasowym, znanym sposobie postepowania, oraz unika sie uciazliwej manipulacji lepkim, oleistym fosforamidem.Sposób wedlug wynalazku ulatwia wiec i znacznie upraszcza otrzymywanie Nn(idjwiu€ityloaminoetylo)-2- metoksy-5-imetylos Podany nizej przyklad objasnia blizej sposób wedlug wynalazku. 85 14285 142 Przyklad.

PL PLThe present invention relates to a process for the preparation of N- (diethylaminoethyl) -2-methoxy-5-methylsulfonylbenzamide of the formula III and its pharmacologically acceptable salts with inorganic and organic acids and its quaternary ammonium salts by reaction 2-methoxy-5-meitylsulfonylbenzoic acid of formula 1, dissolved in solvent, with N, N ', N / r-triliser 2, according to scheme 1. Used as N, N', N "-tris- substituent (diethylamdinoethyl) phosphoramide boiling 2 is obtained by reacting phosphorus oxychloride with diethylaminoethylamine according to Scheme 2. which is separated and converted into the base, and then further processed and reacted with benzoic acid of the formula 1. It is difficult to process, and in particular to clean, difficult. The aim of the invention is to eliminate the disadvantage mentioned. To this end, it is necessary to solve the problem of such a method of carrying out the process by selecting a suitable solvent that it becomes necessary to isolate and purify the fO-JO sphoramide before introducing it into the reaction "in the method according to the invention. This aim is achieved in the method according to the invention, however, pyridine is used as a solvent in the reaction of 2-methoxy-5-methylbenzoic acid of the formula 1 with N, N ', N, - tris-1 (diethylaminoethyl) -phosphoramide of the formula 2. Pyridine is also used in the reaction of the amine. with phosphorus oxychloride (according to Scheme 2) has the advantage that pyridine binds the hydrochloric acid formed and at the same time dissolves the free, oily phosphoramidate of the formula II, thus allowing further direct reaction with the benzoic acid of the formula 1. according to Scheme 1, in one pass and in one reaction vessel. When pyridine is used as a solvent, there is therefore a prior isolation and purification of fdsforamide hydrochloride of the formula II and its cross section basically unnecessary. Due to the use of pyridine as a solvent, at least two procedures necessary in the current, known procedure are eliminated, and the cumbersome manipulation of viscous, oily phosphoramide is avoided. ) -2-methoxy-5-imethyls The following example explains the process according to the invention in more detail. 85 14 285 142 Ex.

Add a solution of 6 to the solution at ambient temperature. 1 g of phosphorus oxychloride in 65 ml of pyridine and the reaction mixture is stirred for half an hour. Then 22.1 g of 2-methoxy-5-methylsulfonylbenzesic acid are added, and the reaction mixture is heated to reflux under cold conditions. and reflux within 4 hours. After the reaction is complete, the pyridine is evaporated off, • 40 m difference! of water and 40 ml of 36% hydrochloric acid to remove any unreacted acid residues. The solution is made alkaline with lye, and the obtained precipitate is filtered off and dried. 9 g of N- (diethylaminoeityl) -2-methoxy-5-methylsulfonylbenzamide with a melting point of 120-122 ° C are obtained. -0 = P (NH CHg-CHg-N ^ -H ^), Scheme 2 Price PLN 10 PIZG Basket mm D-4084.
