## Abstract A modification of the Gould‐Jacobs reaction, particularly useful for the preparation of N‐alkyl‐4‐quinolone‐3‐carboxylic acids, is described. Decarboxylation of these acids leads to N‐alkyl‐4‐quinolones or, in the case of N‐ethyl‐benzo[h]‐4‐quinolone‐3‐carboxylic acid, to 4‐ethoxy‐benzo
