Abstract
2-Alkoxy-6 : 9-dihalogenacridines.-2 : 4 dihalogenbenzoic acids are condensed in the customary manner with 4-alkoxyanilines to give the p 4-alkoxy-31-halogendiphenylamine-61-carboxylic acid, thence the 2-alkoxy-6-halogenacridones and the latter are treated with customary halogenating agents, especially phosphorus pentahalides, to give 2-alkoxy - 6 : 9 - dihalogenacridines. According to examples, 4-anisidine is condensed with 2 : 4-dichlorobenzoic acid, 2-chloro-4-bromobenzoic acid, 2-chloro-4-iodobenzoic acid, and 4-phenetidine with 2 : 4-dichlorobenzoic acid to give the corresponding 2-alkoxy-6-halogenacridones in two stages as stated above, and the products are treated with phosphorus pentachloride, phosphorus oxychloride, iodine and red phosphorus, or phosphorus pentabromide, to give corresponding dihalogenacridines. 2-Chloro-4-iodobenzoic acid is obtained by the Sandmeyer reaction from 2-chloro-4-iodotoluene, followed by oxidation.
