Fluoromethoxybenzene

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 3-Fluoromethoxybenzene (15.8 g, 125 mmol) was stirred at -78° C. in anh. THF (100 mL) and treated with n-BuLi (50 mL, 2.5M hexanes soln., 125 mmol) over 5 min. After stirring below −70° C. for 4 hours, the mixture was treated with cyclopent-3-enecarboxylic acid methoxy-methyl-amide (18.4 g, 119 mmol) dropwise over ˜¼ hour. The mixture was stirred below −70° C. for 1 hour, and then allowed to warm to ambient temperature over ˜1 hour. The mixture was poured into 1N aq. HCl soln. (200 mL) and shaken. The layers were separated and the aq. layer extracted with EtOAc (3×100 mL). The organic layer was washed with H2O (50 mL), sat. aq. NaHCK soln.
