The present invention relates to a compound represented by the formula (1) :
wherein
-A- is
wherein X1 and X2 are each independently a halogen atom,
------¯ is a single bond or a double bond, and
R1, R2 and Z are each as defined in the description, or a salt thereof, a production method thereof and the like. A 2,6-dihalogeno-8-substituted-purine compound or a salt thereof, which is useful as an intermediate for producing medicaments, can be conveniently produced from a 2,6-dihalogenopurine compound or a salt thereof, and a 2,6-dihalogeno-8-substituted-purine compound or a salt thereof can be easily provided.
本发明涉及一种由式(1)表示的化合物:
其中
-A-是
其中 X1 和 X2 各自独立地为卤素原子、
------¯ 是单键或双键,以及
R1、R2 和 Z 各自如描述中所定义,或其盐,其生产方法等。可以方便地从 2,6-二卤代嘌呤化合物或其盐中制备出 2,6-二卤代-8-取代嘌呤化合物或其盐,而 2,6-二卤代-8-取代嘌呤化合物或其盐可作为生产药物的中间体。
