tert-butyl 4-fluoro-2-methylbenzoate

反应条件: temp:130.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of tert-butyl 4-fluoro-2-methylbenzoate (1 g, 4.8 mmol) in methylsulfinylmethane (45 mL) were added phenol (0.43 g, 4.6 mmol) and potassium carbonate (1.24 g, 9 mmol). Then the mixture was stirred at 130° C. for 12 hours. The reaction mixture was poured into water (50 mL) and extracted with ethyl acetate (50 mL). The organic phase was separated, washed with water (20 mL). The organic phase was separated and concentrated to give a residue. The residue was purified by column chromatography (petroleum ether/ethyl acetate=10:1) to give tert-butyl 2-methyl-4-phenoxybenzoate (1.1 g, 86%) as a yellow solid. LRMS (M+H+) m/z: calcd 284.14. found 284. extracted with ethyl acetate (50 mL) The organic phase was separated washed with water (20 mL) The organic phase was separated concentrated to give a residue The residue was purified by column chromatography (petroleum ether/ethyl acetate=10:1)
