乙基2-(2,3,5-三氟苯基)-乙酸酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Ethyl 2-(2,3,5-trifluorophenyl)-acetate (29 g) was slowly added to a mixture of diethylcarbonate (63 g) and sodium hydride (9.5 g) in toluene (350 ml). After being refluxed for 3 hours, the reaction mixture was cooled, treated with ice-water and washed with water. The organic layer was separated, dried and filtered. The filtrate was concentrated in vacuo to yield 32 g of the title compound. After being refluxed for 3 hours the reaction mixture was cooled washed with water The organic layer was separated dried filtered The filtrate was concentrated in vacuo
