Reaktionsschritte

Ethyl bromoacetate (1.2 g, 10.9 mmol) was added in the suspension of 4-nitro-3-trifluoromethyl phenol (2.0 g, 9.66 mmol) and potassium carbonate (2.0 g, 14.5 mmol) in acetone, and the mixture was attired at room temperature for 6 hours. After the reaction mixture had been poured in ice water and acidified with 2N hydrochloric acid, the mixture was extracted with ethyl acetate. The organic layer was washed with 5% sodium hydrogencarbonate aqueous solution and then with water, and dried with anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure, and 4-nitro-3-trifluoromethyl-phenoxyethyl acetate (3.24 g (theoretical amount: 2.83 g), 100%) was obtained as a yellow solid and was used in the next reaction without purification.
