甲基4,4,4 -三氟丁酸

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

实验步骤: To a suspension of NaH (0.512 g, 12.81 mmol) in DME (15 mL) was added a solution of methyl 4,4,4-trifluorobutanoate (1 g, 6.41 mmol) and methyl formate (0.594 mL, 9.61 mmol) in DME (10 mL) dropwise at 0° C. The mixture was stirred at room temperature overnight. After removing the solvent, the residue was diluted with water (50 mL), extracted with ether once, and neutralized to pH<7 by AcOH. The aqueous layer was separated and extracted with EA twice. The combined organic phase was dried over sodium sulfate, filtered, and concentrated to afford the title compound (0.875 g, 4.75 mmol, 74.2% yield). LCMS: rt=2.23 min, [M+H+]=185 After removing the solvent the residue was diluted with water (50 mL) extracted with ether once The aqueous layer was separated extracted with EA twice The combined organic phase was dried over sodium sulfate filtered concentrated
