求翻译：在合成出4，6-二氯-5苯胺基嘧啶之外，还合成出4，6-二氯-5-氨基嘧啶和 4，6-二氯-5-正丁胺基嘧啶。当然，反应其中的溴代产物也是本次实验成功所需的一大支持。是什么意思？

To the synthesis of 4,6 - dichloro-5-anilino pyrimidine synthesis of 4,6 - dichloro-5 - amino-pyrimidine and 4,6 - dichloro-5 - n-butylamine pyrimidine. Of course, the brominated product of the reaction which is needed to succeed in this experiment a great support.

In synthesizes outside 4,6- two chlorine - 5 anilino- pyrimidine, but also synthesizes 4,6- two chlorine - 5- amino pyrimidine and 4,6- two chlorine - 5- Ding amidogen pyrimidine.Certainly, responded bromo product also is a big support which this time tests successfully needs.

4,6-Dichloro-5 synthesis of aniline based outside of pyrimidine, and synthesis of 4,6-chloride -5-amino-pyrimidines and 4,6-amino-pyrimidine n-butyl chloride -5-. Of course, reactive brominated products is also required for this experiment is successful a major support.
