反应条件: temp:0.00; pressure:0.00; stir:

反应条件: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1-Bromo-4-fluoro-2-methoxymethoxy-benzene (7.6 g, 32 mmol) is placed in a pressure flask, dissolved in diethylamine (65 mL) and degassed with nitrogen for 15 min. An excess of butyne is bubbled through the solution, CuI (1.9 g, 10 mmol) and PdCl2(PPh3)2 (2.3 g, 3.3 mmol) are added, and the flask is heated to 70° C. for 44 h. The mixture is diluted with ether, then washed with saturated aqueous NH4Cl and brine. The organic portion is dried over MgSO4, filtered, and concentrated under reduced pressure. The resulting residue is purified by flash chromatography (Biotage® Si65M, 3% THF/hexane) to provide 6.12 g (91%) of the title compound as an orange solid. GCMS m/e 208 [M]+. degassed with nitrogen for 15 min are added washed with saturated aqueous NH4Cl and brine The organic portion is dried over MgSO4 filtered concentrated under reduced pressure The resulting residue is purified by flash chromatography (Biotage® Si65M, 3% THF/hexane)

反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2-Bromo-5-fluorophenol (30 g, 0.16 mol) is dissolved in dichloromethane (170 mL) and cooled to 0° C. To this solution is added diisopropylethylamine (36 mL, 0.20 mol) via syringe followed by chloromethyl methyl ether (16 mL, 0.20 mol) via an addition funnel. The solution is stirred and warmed to room temperature. After 2 h, the mixture is washed with saturated aqueous NH4Cl, water, and brine. The organic portion is dried over MgSO4, filtered, and concentrated under reduced pressure. The resulting residue is purified by flash chromatography (Biotage® Si65M, 20% AcOEt/hexane) to yield 26.1 g (71%) of the title compound as a clear colorless oil. 1H NMR 400 MHz (CDCl3) δ 7.46-7.53 (m, 1H), 6.92-6.99 (m, 1H), 6.63-6.70 (m, 1H), 5.26 (s, 2H), 3.55 (s, 3H). warmed to room temperature the mixture is washed with saturated aqueous NH4Cl, water, and brine The organic portion is dried over MgSO4 filtered concentrated under reduced pressure The resulting residue is purified by flash chromatography (Biotage® Si65M, 20% AcOEt/hexane)
