Disclosed is a process for preparing a 6-chloro-2,5-dicarbonamido phenol compounds comprising a step employing a 2-alkyl-6-aminobenzoxazole to form a 2-alkyl-6-amino-7-chlorobenzoxazole in which the 2-alkyl group is unbranched at the α carbon. It also provides intermediate compounds useful in the process. The process provides a simple and safe way to prepare 6-chloro-2,5-dicarbonamido phenol compounds in good yield.
本发明公开了一种制备6-氯-2,5-二羧酰胺苯酚化合物的方法,包括采用2-烷基-6-氨基苯并咪唑制备2-烷基-6-氨基-7-氯苯并咪唑的步骤,其中2-烷基基团在α碳上为直链。本发明还提供了在该过程中有用的中间体化合物。该方法提供了一种简单而安全的方法来制备6-氯-2,5-二羧酰胺苯酚化合物,收率良好。
