Versuchsvorschrift

3,4-Dichloro-6-aminobenzaldehyde (2.85 g, 15 mmol) was stirred with dimethylmalonate (10 ml) at 140° C. for 20 h. The mixture was diluted with ethyl ether (100 ml). The precipitate was collected, washed twice with ethyl ether and dried in vacuo to give 2.86 g of methyl 6,7-dichloro-2-hydroxyquinoline-3-carboxylate.
