(2,3-二氟苯基) 乙酸甲酯

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

实验步骤: To a solution of 2,3-difluorophenol (30.0 g, 231 mmol) and pyridine (18.6 mL, 231 mmol) in dichloromethane (230 mL) at 0° C. was carefully added acetyl chloride (16.4 mL, 231 mmol). The reaction was allowed to warm to ambient temperature and stirred for 16 hours. The reaction mixture was then diluted with dichloromethane (100 mL), washed with 1N aqueous hydrochloric acid (2×50 mL) and brine (75 mL), and concentrated to produce 41.0 g (100%) of the title compound. MS (DCI/NH3) m/z 190 (M+NH4)+. at 0° C. washed with 1N aqueous hydrochloric acid (2×50 mL) and brine (75 mL) concentrated
