Reaktionsschritte

A solution of 40.5 g. of 2,6-dinitro-4-trifluoromethyl-1-chlorobenzene in 300 ml. of benzene was mixed with 250 ml. of 14 N ammonium hydroxide. The reaction mixture was stirred at room temperature for about 1.5 hours, at which point in time another 100 ml. of 14 N ammonium hydroxide were added and the stirring was continued for an additional 2 hours. The organic layer was separated, was washed with water and was dried. Removal of the solvents in vacuo yielded 2,6-dinitro-4-trifluoromethylaniline, which melted at about 142°-144° C. after recrystallization from a hexane-benzene solvent mixture.
