F. Dumont et G. Slegers, SYNTHESIS OF OMO-5-IODO-4-OXO-1,4-DIHYDROQUINOLINE-2-CARBOXYLIC ACID, Bulletin des Societes chimiques belges, 104(8), 1995, pp. 505-507
The synthesis of omo-5-iodo-4-oxo-1,4-dihydroquinoline-2-carboxylic ac
id 7 is described. The synthesis was started from 2,6-dibromo-4-nitroa
niline and carried out using a modified Conrad-Limpach procedure follo
wed by a nucleophilic non-isotopic exchange.
