方法2:在氮气保护下,向装有四氢呋喃(THF)(40mL)的烧瓶中加入硼氢化钠(1.2g,31.7mmol),启动搅拌。随后,在20分钟内缓慢加入4-联苯基乙酸(5.0g,23.6mmol),保持反应混合物温度在20-30℃。加入THF冲洗液(5mL)后,继续搅拌20分钟。接着,在约1小时内缓慢滴加碘(2.9g,11.4mmol)的THF(10mL)溶液,同时维持反应温度在20-30℃。反应混合物在该温度下继续搅拌约1小时,直至薄层色谱(TLC)分析确认4-联苯乙酸完全转化。反应淬灭通过加入5wt%氢氧化钠水溶液(26mL)实现。充分混合后,静置分液,弃去下层水相。水相用乙酸异丙酯(2×25mL)萃取,合并有机相,用去离子水(4×20mL)洗涤。减压蒸发有机相,得到2-(联苯-4'-基)乙醇,为浅黄色结晶固体(4.6g,收率98.5%)。产物亦可参照方法1所述,通过乙酸异丙酯与庚烷的溶剂交换进行结晶纯化。
