A novel process for preparing 2-halo-6-aminopurine derivatives and their analogs is disclosed. The method comprises halogenation of 2,6-diaminopurine derivatives at the C-2 position in a specific combination of aprotic polar and nonpolar organic solvents to give the corresponding halogenated derivatives.
公开了一种制备2-卤代-6-氨基嘌呤衍生物及其类似物的新型工艺。该方法包括在无极性极性和非极性有机溶剂的特定组合中卤代2,6-二氨基嘌呤衍生物的C-2位置,以得到相应的卤代衍生物。
