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

实验步骤: Method 3 was followed using 2-isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (2.2 equiv.), butyllithium (1.2 equiv.) and 1,3-difluoro-5-isopropoxybenzene (1.0 equiv.) to give 2-(2,6-difluoro-4-isopropoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane in 99% yield. 1H NMR (400 MHz, <cdcl3>) δ ppm 1.24 (s, 12H), 1.31-1.33 (m, 6H), 4.43-4.56 (m, 1H), 6.31-6.44 (m, 2H).

实验步骤: To a solution of 3,5-difluorophenol (1.0 equiv.) in DMF (0.26 M) was added potassium carbonate (2.2 equiv.) followed by 2-iodopropane (1.1 equiv.) and the reaction was stirred overnight at room temperature. The reaction was poured into a separatory funnel and diluted with a 3:1 (v/v) solution of EtOAc:heptanes. The organic phase was washed with water, then sat'd NaHCO3. The remaining organic phase was dried over MgSO4, filtered and concentrated in vacuo to provide 1,3-difluoro-5-isopropoxybenzene in 88% yield. 1H NMR (400 MHz, <cdcl3>) δ ppm 1.33 (d, J=6.26 Hz, 6H), 4.48 (dt, J=11.93, 6.16 Hz, 1H), 6.31-6.47 (m, 3H). The reaction was poured into a separatory funnel The organic phase was washed with water The remaining organic phase was dried over MgSO4 filtered concentrated in vacuo
