Dimethylformamide → (4-Trifluoromethoxyphenoxy)-acetic acid tert-butyl ester

참여 물질

반응 단계

tert-Butyl bromoacetate was added to a stirring suspension of potassium carbonate (14.6 g, 106 mmol), 4-(trifluoromethoxy)phenol (15.7 g, 88 mmol) and DMF (50 mL). The reaction mixture was stirred for 12 hours. The mixture was diluted with EtOAc and water. The layers were separated and the aqueous layer was extracted with 3×EtOAc. The combined organic layers were washed with 5% aqueous lithium chloride and brine, dried over sodium sulfate, filtered, and reduced in vacuo to afford the title compound as a colorless oil: 1H NMR (400 MHz, d6-DMSO): 7.27 (d, 2H), 6.98 (d, 2H), 4.68 (s, 2H), 1.42 (s, 9H).
