a) 3-溴-4-氟苯甲酸甲酯的合成 将3-溴-4-氟苯甲酸（3.33 g，15.2 mmol）溶解于甲醇（30 mL）中，冰浴冷却下缓慢滴加乙酰氯（4.3 mL，60.8 mmol）。反应混合物于室温搅拌20小时。反应完成后，将反应液减压浓缩。粗产物通过硅胶柱色谱法（洗脱剂：己烷/乙酸乙酯）纯化，得到3-溴-4-氟苯甲酸甲酯（3.2 g，收率90%）为无色油状物。1H-NMR (CDCl3) δ: 3.92 (3H, s), 7.18 (1H, dd, J = 8.0, 8.2 Hz), 7.99 (1H, ddd, J = 1.9, 4.9, 8.0 Hz), 8.27 (1H, dd, J = 1.9, 6.5 Hz)。
