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

实验步骤: In a 10 ml flask, under a nitrogen atmosphere, 2-methoxyethanol (0.125 ml, 1.60 mmol) was dissolved in N,N-dimethylformamide (2 ml). Sodium hydride (60%, 72 mg, 1.81 mmol) was added and the mixture was stirred at ambient temperature for about thirty minutes. To this reaction mixture was added 2-fluoro-5-bromobenzyl bromide (285 mg, 1.06 mmol) as a solution in N,N-dimethylformamide (2 ml). The resulting mixture was stirred at ambient temperature for two hours. The progress of the reaction was monitored by thin layer chromatography. The reaction mixture was partitioned between 1 M potassium carbonate and diethyl ether. The aqueous fraction was back extracted with diethyl ether. The organic fractions were combined, washed with brine (7×) and dried over sodium sulfate. The solvents were removed in vacuo. The title intermediate was used without further purification. The resulting mixture was stirred at ambient temperature for two hours The reaction mixture was partitioned between 1 M potassium carbonate and diethyl ether The aqueous fraction was back extracted with diethyl ether washed with brine (7×) dried over sodium sulfate The solvents were removed in vacuo The title intermediate was used without further purification
