Opfindelsen angår en analogifremgangsmåde til fremstilling af et hidtil ukendt antibakterielt middel og nærmere 9-halogen-7-oxo-2,3-dihydro-7H-pyrido[1,2,3-de][1,4]benzoxazin-6-carboxylsyrederivater med formlen I

10 hvori R betegner hydrogen eller en alkylgruppe med 1-2 carbon-15 atomer; Z betegner en pyrrolidinyl-, piperidinyl- eller pipera-zinylgruppe, der eventuelt er substitueret med en hydroxy-, methyl- eller ethylgruppe; og X betegner et halogenatom; 20 eller farmaceutisk acceptable salte deraf.
USA-Patenterne nr. 3.883.522 og 3,984.548 beskriver 9-fluor-3-methyl-7-oxo-2,3-dihydro-7H-pyrido-[1,2,3-de] [l,4]benzoxazin-6-carboxylsyre, japansk patentansøgning (OPI) nr. 138582/1979 beskriver 1-ethyl-25 6-fluor-7-(4-methyl-l-piperazinyl)-4-oxo-l,4-dihydro-quinolin-3-carboxylsyre og japansk patentansøgning (OPI) nr. 76875/1980 beskriver 8-(4-methyl-l-piperazinyl)-9-fluor-5-methyl-6,7-dihydro-l-oxo-lH,5H-benz[ij]quinoli-din-2-carboxylsyre (udtrykket "OPI" angiver en "offent-30 liggjort ikke undersøgt patentansøgning"). Se i øvrigt DE OS 29 14 258.
Den omhandlede forbindelse kan danne et syreadditionssalt med en uorganisk eller organisk syre såsom salt-, svovl-, methansulfonsyre og lignende og 35 kan danne det tilsvarende carboxylat med natrium, kalium og lignende. I sammenligning med de ovennævnte kendte forbindelse har forbindelserne ifølge opfindelsen bedre antibakteriel virkning overfor gram-negative 2

og gram-positive bakterier samt lavere toxicitet.
Forbindelserne fremstilles ifølge opfindelsen ved nedennævnte reaktion.

hvori X, R og Z har de ovennævnte betydninger. Omsætningen kan udføres ved at opvarme en forbindelse med formlen II med en amin med formlen III ved en tempe-15 ratur på fra ca. 30°C til 200°C, og fortrinsvis fra 70°C til 150°C, i nærværelse af et egnet organisk polært opløsningsmiddel såsom dimethylsulfoxid, sulfolan, dimethylformamid, dimethylacetamid eller vand. Det er 20 ønskeligt at udføre omsætningen i nærværelse af en syreacceptor såsom triethylamin, dimethylanilin, ka-liumcarbonat og lignende med et molforhold på 1,0 til 1,2 mol syreacceptor pr. mol forbindelse med formlen II. Eftersom udgangsmaterialet med formlen III i sig selv 25 er en amin, kan det også optræde som syreacceptoren.
I et sådant tilfælde er det ønskeligt at anvende to eller flere mol af aminen med formlen III til et mol af forbindelsen med formlen II. Såfremt der anvendes en anden syreacceptor såsom triethylamin, kan det være 30 tilstrækkeligt at anvende aminen med formlen III i et molforhold på 1,0 til 1,2 mol pr. mol forbindelse med formlen II.
Omsætningen afsluttes normalt på et tidsrum på fra 1 til 48 timer, og produktet kan isoleres og renses 35 ved kendte teknikker såsom inddampning, filtrering, ekstraktion, chromatografi, omkrystallisation samt en kombination deraf. F.eks. opsamles produktet, såfremt det udfældes ved afkøling af reaktionsblandingen,ved 3

filtrering,og såfremt udfældning ikke finder sted, koncentreres reaktionsblandingen til tørhed under reduceret tryk,og resten omrystes med en blanding af chloroform og vand, hvorefter produktet opnås ved koncentra-5 tion af chloroformlaget. I det tilfælde, hvor produktet er farvet eller indeholder nogle biprodukter, kan . yderligere rensning udføres ved silicagelchromatografi eller omkrystallisation. Udgangsforbindelser med formlen II i fremgangsmåden ifølge opfindelsen til fremstil- 10 ling af de omhandlede forbindelser er hidtil ukendte forbindelser og kan fremstilles ud fra kendte forbindelser (A) [J. Amer. Chem. Soc., 8J_, 94-101 ( 1959)] ved den fremgangsmåde, der er skitseret nedenfor.
