Description
Przedmiotem wynalazku jest sposób wytwarza¬ nia N-[(l-etylopirolidynylo-2) - metylo]-2-metoksy- -5-sulfamoilobenzamidu z l-etylo-2-aminometylopi- rolidyny i kwasu 2-metoksy-5-sulfamoilobenzoeso- wego, stanowiacej cenny produkt do wytwarzania innych leków, zwlaszcza leków schorzen z zakresu gastro-enterologii jak i neurologii.Sposoby wytwarzania pochodnych N-[(l-etylopi- rolidynylo - 2)-imetylo - 2-metoksy - 5-isulfamoilo- benzamidu znane dotychczas z publikacji Urzedu Patentowego Republiki Federalnej Niemiec nr 1595915 i opisów patentowych Niemieckiej Republi¬ ki Demokratycznej nr nr 60756 i 60757 polegaly dotychczas na stosowaniu chlorków kwasowych lub innych pochodnych kwasu benzoesowego.Sposoby te charakteryzuja sie wiec ta wada, ze wymagaja dodatkowego wytworzenia odpowiedniej pochodnej kwasu benzoesowego, która dopiero po- tym kondensuje sie z aminometylopirolidyna.Stwierdzono, ze mozna uniknac powyzszego zbe¬ dnego etapu, jesli l-etylo-2-aminometylopirolidyne poddaje sie reakcji z kwasem 2-metoksy-5-sulfa- moilobenzoesowym, w obecnosci trójchlorku fosfo¬ ru. ja'ko srodowisko reakcji stosuje sie korzystnie pirydyne.Sposób wedlug wynalazku charakteryzuje sie ta zaleta, ze jest jednoetapowy, jak i tym, ze umozli¬ wia uzyskania produktu ze znacznie wyzsza wy¬ dajnoscia, jak i o wyzszej jakosci stwierdzonej za pomoca oznaczenia temperatury topnienia.Sposób wedlug wynalazku ilustruje zalaczony schemat reakcji, jak i wyjasnia nizej podany przy¬ klad.Przyklad. W kolbie o pojemnosci 1 litra, wyposazonej w mieszadlo, chlodnice, termometr i wkraplacz, umieszcza sie 27 g (0,11 mola) 1-etylo- -2-aminometylopirolidyny i 560 ml pirydyny.Otrzymany roztwór miesza sie i dodaje do niego po kropli 5,6 g (0,04 mola) trójchlorku fosforu roz¬ puszczonego w 64 ml pirydyny, przy czym utrzy¬ muje sie temperature 20°C. Nastepnie miesza sie nadal w ciagu 0,5 godziny w temperaturze 20°C, po czym dodaje sie 14,8 g (0,064 mola) kwasu 2- -metoksy-5-sulfamoilobenzoesowego.Calosc ogrzewa sie pod chlodnica zwrotna w ciagu 4,5 godzin, po czym odstawia sie mieszanine reakcyjna na noc. Nastepnie oddestylowuje sie pi¬ rydyne pod zmniejszonym cisnieniem, a pozostalosc ekstrahuje sie 200 ml 10% kwasu solnego. Otrzy¬ muje sie osad, który ogrzewa sie do temperatury okolo 70—80°C, przy czym osad ten rozpuszcza sie.Do otrzymanego roztworu dodaje sie 15 ml stezo¬ nego amoniaku. Wytworzony osad odsacza sie, przemywa woda i suszy w suszarce szafkowej w temperaturze 50°C.Otrzymuje sie 16,2 g ( = 74,3% wydajnosci) N- -[i(l-etylopirolidynylo - 2)-metylo]-2-metoksy-5-sul- famoilobenzamidu o temperaturze topnienia 178°C. 84 44684 446 PL PL
