Ethanol → Ethyl 3-nitro-4-(trifluoromethyl)benzoate

참여 물질

반응 단계

3-Nitro-4-(trifluoromethyl)benzoic acid (10 g, 43 mmol) was taken up in 100 ml of ethanol and sulfuric acid (11 ml) was added to the mixture. The reaction was heated to reflux for 12 hours. The volatiles were removed in vacuo. The residue obtained was diluted with ethyl acetate and water. The layers were separated and the organic layer was washed with an aqueous solution of saturated sodium bicarbonate, water and brine. The organic layer was then dried with sodium sulfate and the volatiles removed in vacuo to give ethyl 3-nitro-4-(trifluoromethyl)benzoate a clear yellow oil.
