A suspension of 12.7 g (60 mmols) of 3-chloro-4-trifluoromethoxyaniline and 15.15 g (60 mmols) of 1-chloro-2,4-dinitronaphthalene in 150 ml of water was heated to the boil. 5.6 g (67 mmols) of sodium bicarbonate were introduced in the course of 30 minutes and heating was continued for 2 hours under reflux. After the mixture had cooled to 20° C., the product was filtered off. 24 g of 1-(3-chloro-4-trifluoromethoxyphenylamino)-2,4-dinitronaphthalene of melting point 140° C. were obtained; after recrystallization from ethanol, 17.4 g of melting point 159° C. were obtained.
