deprotonation of 1-(N,N-dimethylaminomethyl)2-methylimidazole 4 by n-butyllithium yields anion 5 which can readily undergo alkylation reactions. This finding provides immediate access to 2-(2-arylethyl)imidazoles, 1, which are clumsy to prepare by other methods.
1-(N,N-二甲基氨基甲基)2-甲基咪唑4被正丁基锂直接去质子化生成的阴离子5可以很容易地进行烷基化反应。该发现提供了立即获得2-(2-芳基乙基)咪唑1的方法,它们很难通过其他方法制备。
