以化合物(CAS:217476-14-7)(61.9g)為原料,在氮?dú)獗Wo(hù)下,將其與甲酸(120g)和甲苯(120ml)加入反應(yīng)容器中。加熱回流反應(yīng)3小時(shí)后,緩慢冷卻至室溫。向反應(yīng)混合物中加入水(300ml)和甲苯(300ml),充分混合后靜置,待其分層為有機(jī)相和水相。分離有機(jī)相,依次用飽和碳酸氫鈉水溶液和水洗滌,隨后用無水硫酸鎂干燥。減壓蒸餾除去溶劑,殘余物通過柱色譜法純化,使用甲苯與乙酸乙酯的混合溶劑(甲苯:乙酸乙酯=9:1,體積比)作為洗脫劑,硅膠作為固定相。收集目標(biāo)組分,干燥后得到47.2g 4-(3-氟苯基)環(huán)己酮(19),產(chǎn)率為93.7%(基于化合物(18)計(jì)算)。
