A stirred mixture of 2-amino-5-iodobenzaldehyde (2.0 g), ethyl nitroacetate (4.2 g), and piperidine (0.7 g) was heated under reflux for 1.5 hours in o-xylene (100 cm3). The cooled solution was then concentrated in vacuo and the solid residue was recrystallised from chloroform-isopropanol to afford 6-iodo-3-nitro-2-(1H)-quinolone, m.p. 279°-282°, (1.14 g).
