Prepared from 5.00 g of 4-chloro-6-nitroquinoline-3-carbonitrile, 5.38 g of 3-dimethylaminoaniline dihydrochloride and 5.17 g of triethylamine in the same manner as Example 377. The crude product was taken up in EtOAc, treated with Darco, filtered through Celite, evaporated and dried in vacuo (50° C.). The yield of 4-(3-dimethylaminophenylamino)-6-nitroquinoline-3-carbonitrile was 5.62 g as brick red crystals: mass spectrum (electrospray, m/e): M+H 334.2.
