N,N-二乙基氨基乙基-4-甲基苄基醚及其类似物的合成
Syntheses of N,N-Diethylaminoethyl-4-methylbenzyl Ether and Its Analogues
【摘要】 采用相转移催化的方法合成了5个N,N-二烷基氨基乙基-4-甲基苄基醚化合物,产率为73%~89%。适宜的反应条件是:以二烷基氨基乙醇、4-甲基氯化苄为原料,四丁基溴化铵为相转移催化剂(PTC),氢氧化钠为碱,甲苯为溶剂,摩尔比n(R1R2NCH2CH2OH)∶n(MeArCH2C1)∶n(NaOH)∶n(PTC)=1.1∶1∶2∶0.05,反应时间为2 h,温度为70℃。产物经过沸点、元素分析、红外光谱、氢质子核磁共振谱给予确证。
【Abstract】 Five compounds N,N-dialkylaminoethyl-4-methylbenzyl ether were synthesized with good yield(73%~89%)from the reaction of dialkylaminoethanol with 4-methylbenzyl chloride by using Bu4NBr as a phase-transfer catalyst,sodium hydroxide as base,toluene as solvent molar ration n(R1R2NCH2CH2OH): n(MeArCH2Cl)∶n(NaOH)∶n(PTC)=1.1∶1∶2∶0.05,for 2 h at 70(℃).Structure of the products was confirmed by bp determination,elemental analysis,IR and 1H NMR spectrometry.
