| titleOfInvention | PROCEDURE FOR OBTAINING BENZONAFTIRIDINE. |
| abstract | Procedure for obtaining benzonaphthyridine of formula I ** (See formula) ** wherein R1 is hydrogen, C1-3alkyl, C1-3alkoxy or C1-3alkylthio, fluorine, chlorine, bromine, nitro, trifluoromethyl, amino or 2-4 amido carbon atoms, R2 is hydrogen, chlorine, alkyl of 1 to 3 carbon atoms or alkoxy of 1 to 3 carbon atoms, and R3 and R4 signify each other hydrogen or methoxy, or R3 and R4 together are methylenedioxy, characterized by that a 3,4-cis-substituted compound of formula II is cyclized, ** (See formula) ** where R2, R3, and R4 have the meanings indicated above, and RI1 is hydrogen, alkyl of 1 to 3 carbon atoms, alkoxy of 1 to 3 carbon atoms or alkylthio of 1 to 3 carbon atoms, fluorine, chlorine, bromine, nitro or trifluoromethyl, with a dehydrating condensing agent, acid, to obtain a compound of formula Ia, ** (See formula) ** where RI1, R2, R3 and R4 have the meanings indicated above.
