Ethyl 2-chlorophenyl[2,4-dinitro-6-(trifluoromethyl)phenyl]carbamate (0.645 g) was dissolved in ethyl acetate (100 ml), and to the solution was added 10% Pd—C (0.58 g). The reaction mixture was stirred under hydrogen atmosphere for 11 hours. The catalyst was filtered, and washed with ethyl acetate. The filtrate and washing were combined and concentrated in vacuo to give the title compound (0.543 g, 98%).
