以6-溴-2H-1,4-苯并噁嗪-3(4H)-酮（2.3g，10mmol）和聯(lián)硼酸頻那醇酯（3.05g，12mmol）為原料，在二惡烷（20mL）中溶解后，依次加入乙酸鉀（2g，20mmol）和Pd(dppf)Cl2（730mg，1mmol）。反應(yīng)體系經(jīng)氮?dú)獯祾吆?，?0℃下攪拌反應(yīng)過夜。反應(yīng)完成后，將混合物用乙酸乙酯（200mL）稀釋并過濾。有機(jī)相依次用鹽水洗滌，無水硫酸鈉干燥，減壓濃縮得到粗產(chǎn)物。粗產(chǎn)物通過硅膠柱色譜（洗脫劑：石油醚/乙酸乙酯=3:1）純化，得到3-氧代-2H,4H-苯并[b][1,4]噁嗪-6-硼酸頻哪醇酯（1.9g，收率69%）。
