Ethyl 4-chlorobenzyl[2,4-dinitro-6-(trifluoromethyl)phenyl]carbamate (294.7 mg) was dissolved in ethyl acetate (20 ml), and to the solution was added 10% Pd—C (267.7 mg). The reaction mixture was stirred under hydrogen atmosphere for 7 hours. The catalyst was filtered, and washed with ethyl acetate. The filtrate was concentrated in vacuo to give the title compound (248.7 mg).
