1-乙基-1H-吡唑-4-硼酸频那醇酯性质、用途与生产工艺
生产方法
向4-(4,4,5,5-四甲基-1,3,2-二氧杂硼杂环戊烷-2-基)-1H-吡唑（1.0g，5.2mmol）的N,N-二甲基甲酰胺（DMF，10mL）溶液中加入碳酸铯（2.5g，7.7mmol）和碘乙烷（1.2mL，15mmol）。将反应混合物在室温下搅拌12小时。反应完成后，用水（30mL）稀释反应混合物。用二氯甲烷（DCM，30mL×3）萃取水相。合并有机层，用无水硫酸钠（Na2SO4）干燥，随后在减压下浓缩。通过硅胶柱色谱法纯化残余物，使用石油醚（PE）/乙酸乙酯（EtOAc）（体积比2:1）作为洗脱剂，得到无色油状产物1-乙基-1H-吡唑-4-硼酸频哪醇酯（880mg，产率77%）。质谱（MS）分析（电喷雾电离，阳离子模式）显示m/z：223.25 [M + 1]+。
