While methyl N-(4-nitrobenzyl)pyroglutamate can be obtained from methyl N-trimethylsilylpyroglutamate, the best way to obtain methyl N-(2-nitrobenzyl)pyroglutamate is to react 4-nitro benzyl bromide with the iminoether derived from methyl pyroglutamate.
虽然可以从N-三甲基甲硅烷基焦谷氨酸甲酯获得N-(4-硝基苄基)焦谷氨酸甲酯,但是获得N-(2-硝基苄基)焦谷氨酸甲酯的最好方法是使4-硝基苄基溴与衍生自焦谷氨酸甲酯的亚氨基醚反应。
