Process for the synthesis of 2,5-dicarbonamidophenolic couplers and benzoxazole derivatives as intermediates

摘要

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.
