Abstract

1-alkyl-4-oxo- 1,4-di:hydro-quinoliNe carboxylic-acid-ester of formula (I) where R = R1 = 1-4C alkyl gps. R2,R3,R4 may be identical or different gps. of hydrogen or halogen atoms, but at least one substituent should be other than hydrogen, is prepd. by N-alkylating a quinoline-3-carboxylic acid ester of formula (II), - where R1,R2,R3 and R4 as above - with a tri-alkyl-phosphate (RO)3PO (III) - where R = 1-4C alkyl gp. - in the presence of an acid scavenger and at 10-280 deg.C.
