PREPARATION PROCESS OF ACYLAMINO DERIVATIVES

摘要

Process for preparing 2-acylamino oxazoles useful in the treatment of immediate hypersensitivity conditions which process involves the nucleophilic displacement of the 2-substituent of an oxaxolyl intermediate by the anion -NR1COR2(-) derived from the salt ??R1COR2, where M represents a metal cation and NR1COR2 represents the acylamino moiety.
