摘要
以廉价的对氯苯甲腈和对甲苯酚为原料,经过醚化、还原反应合成了目标化合物4-(4-甲基苯氧基)苄胺,目标化合物的结构经IR和NMR确证。考察了不同还原体系、物料比及反应时间对产品收率的影响。确定了最佳反应条件:以四氢呋喃为溶剂,在回流状态下,n(NaBH4)∶n(BF3-Et2O)∶n(4-(4-甲基苯氧基)苯甲腈)=1.2∶1.0∶1.0时,反应时间为18h,总收率达69.3%。该法具有原料易得、操作简单、反应条件温和、不需要特殊设备、产率高等优点。
4-(4-methylphenoxy)benzylamine was synthesized by the reaction of etherification and reduction with the starting materials of p-chlorobenzonitrile and p-cresol. The target compound was identified by IR and NMR. The total yield of the title compound is 69. 3%, which is obtained under optimized conditions., n(NaBH4 ) : n(BF3-Et20) : n(4-(4-methylphenoxy) ben- zonitrile) =1.2 : 1.0 : 1.0, reaction temperature of reflux condition and reaction time of 18 h. The present method has the ad- vantages of availability of starting materials, mild reaction condition, convenient manipulation, non-special equipment and good yield.
