4-氟-5-碘-2-甲基苯酚

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

实验步骤: To 122C (1 g, 4 mmol) in acetone (20 mL) was added K2CO3 (1.64 g) and iodomethane (0.75 mL). The mixture was stirred at rt for 3 h. After TLC (10% EtOAc/Hexane) indicated the reaction was complete, the mixture was diluted with diethyl ether, washed with water and brine. The organic layer was dried over MgSO4 and concentrated. The crude product was purified by silica gel chromatography to give 122D (0.75 g, 70% yield). 1H NMR (400 MHz, CDCl3) δ ppm 2.16 (s, 3H) 3.78 (s, 3H) 6.85 (d, J=8.79 Hz, 1H) 7.05 (d, J=5.27 Hz, 1H). washed with water and brine The organic layer was dried over MgSO4 concentrated The crude product was purified by silica gel chromatography
