2-(二氟甲基)苯甲酸甲酯

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

实验步骤: A mixture of methyl 2-(difluoromethyl)benzoate 52 (7 g, 38 mmol) and 10% aq. NaOH (100 mL) in MeOH (50 mL) was heated at reflux for 30 min. The pH was adjusted to 4 by the addition of 3N HCl. The resulting solid was collected by filtration, rinsed with H2O and dried to give 53 (6 g, 93% yield). was heated at reflux for 30 min The resulting solid was collected by filtration rinsed with H2O dried

实验步骤: To a solution of methyl 2-(difluoromethyl)benzoate (700 mg, 3.76 mmol) in THF was added 1M lithium aluminum hydride in THF (5.64 mL, 11.3 mmol) dropwise at room temperature for 1 h. The reaction was then poured into ice water (100 mL) and diluted with ethyl acetate (200 mL) and 2N sodium hydroxide aqueous solution (100 mL). The organic phase was then separated and washed with brine (50 mL), dried over sodium sulfate and concentrated, to give (2-(difluoromethyl)phenyl)methanol as an oil (480 mg). 1H NMR (400 MHz, CDCl3) δ 7.56 (d, 1H), 7.41 (m, 3H), 6.93 (t, 1H), 4.82 (s, 2H). The organic phase was then separated washed with brine (50 mL) dried over sodium sulfate concentrated
