1-(2,2-二乙氧基乙氧基)-2-氟苯

反应条件: temp:0.00; pressure:0.00; stir:

反应条件: temp:110.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A stirred mixture of 2-fluorophenol (1.00 g, 8.92 mmol), 2-bromo-1,1-diethoxyethane (1.75 g, 8.92 mmol), and K2CO3 (1.47 g, 10.7 mmol) in anhydrous DMF (10 mL) was heated at 110° C. overnight. The reaction mixture was poured into ice cold water (15 mL) and extracted with EtOAc (2×100 mL). The EtOAc solution was washed with water (25 mL) and brine (25 mL), dried over anhydrous Na2SO4, filtered, and evaporated to dryness under reduced pressure. The residue was purified by MPLC on silica gel using a mixture of EtOAc and hexane as eluent to give 1-(2,2-diethoxyethoxy)-2-fluorobenzene (1.65 g, 81%) as a viscous liquid. 1H NMR (400 MHz, CDCl3): δ 7.09-6.96 (m, 3H), 6.93-6.87 (m, 1H), 4.85 (t, 1H, J=5.2 Hz), 4.07 (d, 2H, J=5.2 Hz), 3.82-3.74 (m, 2H), 3.69-3.61 (m, 2H), 1.24 (t, 6H, J=7.0 Hz). extracted with EtOAc (2×100 mL) The EtOAc solution was washed with water (25 mL) and brine (25 mL) dried over anhydrous Na2SO4 filtered evaporated to dryness under reduced pressure The residue was purified by MPLC on silica gel using a mixture of EtOAc and hexane as eluent
