实验步骤: The title compound was prepared in an analogous fashion to that described in Stage 185.2 using 5-bromo-6-chloro-nicotinic acid and 3-chloro-4-(trifluoromethoxy)aniline to afford an off-white crystalline solid. HPLC (Condition 4) tR=6.72 min, UPLC-MS (Condition 3) tR=1.34 min, m/z=429.0 [M−H]−. to afford an off-white crystalline solid

反应条件: temp:20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 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. was heated to the boil heating under reflux the product was filtered off
