- W2371566216 abstract "4-(6-Aminohexyloxy)-4′-cyanobiphenyl(Ⅳ) was synthesized from 4-hydroxy-4′-cyanobiphenyl(Ⅰ) in three steps.Firstly,Ⅰ etherified with 1,6-dibromohexane to form 4-(6-bromohexyloxy)-4′-cyanobiphenyl(Ⅱ) in the presence of potassium carbonate.Then Ⅱ reacted with potassium phthalimide to give 4-(6-phthalimidohexyloxy)-4′-cyanobiphenyl(Ⅲ).Finally,Ⅳ was obtained by hydrazinolysis of Ⅲ.The total yield reached as high as 55.2% compared with 27.8% in the literature~([2]),at the same time the procedure was simplified.Structures of the target product(Ⅳ)and intermediates(Ⅱ,Ⅲ) were confirmed by IR,~1HNMR and elementary analysis.Melting point and clearing point of Ⅳ were 87 ℃ and 104 ℃ respectively by DSC.Compound Ⅳ reacted with dry HCl to give the corresponding salt for application and conservation." @default.
