Hydrolysen kan udføres i surt miljø, f.eks. med HBr i iseddike, eller i alkalisk miljø, f.eks. med et alkalimetal-hydroxid såsom NaOH eller KOH eller med Ba(OH)2 i vandig alkohol.
Hydrolysen foretages fortrinsvis ved reaktionsblandingens tilbage-

De frie baser kan på i og for sig kendt måde omdannes til syreadditionssalte deraf og omvendt. Således kan forbindelserne med formlen I danne syreadditionssalte f.eks. med uorganiske syrer såsom hydrogenchlorid eller med organiske syrer såsom maleinsyre.

F.eks. kan forbindelserne med formlen VIII behandles med reduktionsmidler såsom TiCl3 eller SnCl2 i sur vandig opløsning ved temperaturer mellem stuetemperatur og ca. 60°C. Til fremstilling af forbindelserne med formlen Ild kan også anvendes en hydrogenoly-tisk reduktion af nitrogruppen, f.eks. med hydrogen i nærværelse af en katalysator såsom Raney-nikkel eller palladium/kul i et inert opløsningsmiddel, f.eks. ethanol eller dimethylformamid, ved mellem stuetemperatur og ca. 50°C. I sidstnævnte tilfælde kan dog halogen-3 3 atomer (R ) eller benzylgrupper (R ) fraspaltes, ligesom alkenyl-eller alkynylgrupper (R ) kan omsættes til alkylgrupper.
Udgangsprodukterne med formlen VIII kan fremstilles analogt med fremgangsmåde a') og b').
Forbindelserne med formlen I og de fysiologisk tolerable salte deraf udmærker sig ved interessante farmakologiske egenskaber og kan derfor anvendes som lægemidler.
Forbindelserne har især en dinatrium-chromoglycat (DSCG)-lignende virkning. På grund af denne DSCG-lignende virkning kan forbindelserne anvendes til profylakse og terapi af allergisk og af anstrengelse betinget astma samt til profylakse af allergiske lidelser. Den DSCG-lignende virkning kan vises ved den passive cutane ar.aphylaxi--test (I. Mota, immunology 7, 681, 1964), hvor der måles den af forbindelserne bevirkede hæmning af en antigen-antistof-reaktion. I nedenstående tabel er angivet de af de omhandlede forbindelser bevirkede hæmninger, målt som den procentvise hæmning af en farvet antigen-antistof-reaktionsplets diameter efter administration af 5,6 mg af forbindelsen pr. kg. intravenøst til rotter.

Fremgangsmåden ifølge opfindelsen belyses nærmere ved nedenstående eksempler:
Eksempel 1.
1.2.3.4- Tetrahydro-4-methyl-9H-pyrrolo[3,4-b]quinolin-9-on.
En blanding af 10 g 2-benzoyl-l,2,3,4-tetrahydro-4-methyl-9H-pyr-rolo[3,4-b]quinolin-9-on, 10 g kaliumhydroxid, 10 ml vand og 100 ml ethanol opvarmes i 17 timer til kogning under tilbagesvaling, afkøles, fortyndes med 50 ml ether og 50 ml vand og filtreres.
Ved omkrystallisation af remanensen af methanol og ether fås 1.2.3.4- tetrahydro-4-methyl-9H-pyrrolo[3,4-b]quinolin-9-on, smeltepunkt 209 - 213°C (sønderdeling).
Det som udgangsmateriale anvendte 2-benzoyl-l,2,3,4-tetrahydro-4--methyl-9H-pyrrolo[3,4-b]quinolin-9-on kan fremstilles på følgende måde: 9 143802 a) 3-Anilino-l-benzoyl-2,5-dihydro-lH-pyrrol-4-carboxylsyreethyl-ester.
En blanding af 100 g l-benzoyl-3-oxopyrrolidin-4-carboxylsyreethyl-ester, 42 ml anilin og 23 ml myresyre i 1,2 liter ethanol opvarmes i 15 timer til kogning under tilbagesvaling og inddampes, og remanensen krystalliseres af ether-methylenchlorid. Der fås 3-anilino--1-benzoy1-2,5-dihydro-lH-pyrrol-4-carboxylsyreethylester, smeltepunkt 149 - 151°C.
b) 2-Benzoyl-l,2,3,4-tetrahydro-9H-pyrrolo[3,4-b]quinolin-9-on.
50 g af den således vundne 3-anilino-l-benzoyl-2,5-dihydro-lH--pyrrol-4-carboxylsyreethylester opvarmes i 1 1/2 time til tilbagesvaling i 500 ml diphenylether, medens det dannede ethanol kontinuerligt afdestilleres.
Efter afkøling isoleres det dannede bundfald ved sugefiltrering, eftervaskes med ether og tørres. Der fås 2-benzoyl-l,2,3,4-tetra-hydro-9H-pyrrolo[3,4-b]quinolin-9-on, smeltepunkt 275°C.
c) 2-Benzoyl-l,2,3,4-tetrahydro-4-methyl-9H-pyrrolo[3,4-b]quinolin--9-on.
14,51 g (50 millimol) af det således vundne 2-benzoyl-l,2,3,4-tetra-hydro-9H-pyrrolo[3,4-b]quinolin-9-on opløses i 50 ml af en IN opløsning af natriummethylat i absolut methanol, opløsningen inddampes, og remanensen optages i 150 ml dimethylformamid og tilsættes 3,15 ml methyliodid. Efter 4 timers omrøring ved stuetemperatur sættes der til blandingen ca. 100 ml vand, blandingen filtreres, og remanensen vaskes med vand og tørres. Der fås på denne måde det i eksempel 1 anvendte 2-benzoyl-l,2,3,4-tetrahydro-4-methyl-9H-pyrrolo-[3,4-b]quinolin-9-on, smeltepunkt 285°C (sønderdeling).
