Reaktionsschritte

Ethyl 4-bromo-2-nitro-6-(trifluoromethyl)phenylcarbamate (475.5 mg) was dissolved in N,N-dimethylformamide (10 ml), and to the solution were added potassium carbonate (220.9 mg) and 2-chlorobenzyl bromide (0.207 ml). Then the mixture was heated at 50° C. and stirred for 1 hour. After allowing to cool, to the reaction mixture was added saturated brine, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated in vacuo to give the title compound (757.2 mg, quantitative yield).
