以5-溴-1,3-二甲基吡啶-2(1H)-酮和联硼酸频那醇酯为原料合成1,3-二甲基吡啶-2(1H)-酮-5-频哪醇硼酸酯的一般步骤如下:首先,将氮气通入二恶烷中进行脱气处理。随后,将脱气后的二恶烷溶液(2.0 mL)加入到含有5-溴-1,3-二甲基吡啶-2(1H)-酮(75 mg,0.37 mmol)、双(频哪醇)二硼(113 mg,0.445 mmol)和KOAc(109 mg,1.11 mmol)的混合物中。接着,加入催化剂PdCl2(dppf)·CH2Cl2(30 mg,0.037 mmol)。将反应混合物在85℃下加热反应16小时。反应完成后,用EtOAc稀释反应混合物,并通过Celite垫过滤。最后,将滤液在真空下浓缩,得到粗产物1,3-二甲基吡啶-2(1H)-酮-5-频哪醇硼酸酯(169 mg,0.678 mmol,定量收率),为棕色油状物。
