用途
1,4-二[2-(4-甲基-5-苯基惡唑)]苯可用作醫(yī)藥合成中間體。制備
在N2中向螺旋蓋管中加入5-(三嗪基氧基)惡唑3aa(100mg,0.318mmol),4-乙氧基羰基苯硼酸(4b,246mg,1.27mmol),NiCl2(dppf)(10.9mg,0.0159mmol),K3PO4(473mg,2.23),LiCl(40.4mg,0.954mmol),DPPF(8.8mg,0.0159mmol)和甲苯(2.3mL)?;旌衔锖笤?10℃下攪拌6小時(shí),將反應(yīng)混合物冷卻至室溫。稀釋反應(yīng)混合物,將CH2Cl2(10mL)過濾通過短硅藻土墊,并將濾液減壓濃縮。該通過快速柱色譜法(EtOAc:己烷=10:90)純化殘余物,得到1,4-二[2-(4-甲基-5-苯基惡唑)]苯5aab(62.5mg,64%),為白色固體。1,4-二[2-(4-甲基-5-苯基惡唑)]苯價(jià)格(試劑級(jí))
