反应详情

To 10 ml DMF is added 0.88 g 3-(2,2,2-trifluoroethoxy)-2,2-dimethylcyclopropanecarboxylic acid (4.14 mmol) and 1.146 g potassium carbonate (8.29 mmol), after which is added 1.2 g 4-fluoro-3-phenoxybenzyl bromide. This mixture is stirred under nitrogen for 15 hours. The reaction mixture is extracted with ether and the ether phase is washed with water (3×) and brine, and dried over sodium sulfate. The solvent is then removed to yield 4-fluoro-3-phenoxybenzyl 3-(2,2,2-trifluoroethoxy)-2,2-dimethylcyclopropanecarboxylate.
