Disclosed is a process for preparing 2,5-dicarbonamido phenol compounds comprising a step employing a 2-alkyl-6-nitro-benzoxazole to form a 2-alkyl-6-amino-benzoxazole in which the 2-alkyl group is unbranched at the a carbon. It also provides intermediate compounds useful in the process. The process provides a simple and safe way to prepare 2,5-dicarbonamido phenol compounds in good yield.
本发明公开了一种制备 2,5-二甲酰胺基苯酚化合物的工艺,该工艺包括一个步骤,使用 2-烷基-6-硝基苯并噁唑形成 2-烷基-6-氨基苯并噁唑,其中 2-烷基在一个碳上未分支。它还提供了该工艺中有用的中间化合物。该工艺为制备 2,5-二甲酰胺基苯酚化合物提供了一种简单、安全且收率高的方法。
