실험 절차

The 2-chloro-3-nitro-5-trifluoromethylbenzoyl chloride (5.5 g; 18 mmol), obtained in step b) of Example 1, is dissolved in ethanol (50 ml) and stirred for 1 hour at room temperature. After evaporating to dryness, the pasty solid is purified by filtration on silica (eluent: dichloromethane). 4.2 g of ethyl 2-chloro-3-nitro-5-trifluoromethylbenzoate are obtained in the form of a pale yellow oil.
