Synthesis of N-p-Hydroxybenzoyl-N'-aryl-ureas on a Traceless Linker Derived Soluble Polymer Support
Abstract:
N-p-Hydroxybenzoyl-N'-aryl-ureas (Ⅶ) were prepared in CH2Cl2 or DMF using oxalyl chloride as traceless linker and poly (ethylene glycol) as soluble polymer support with yields of 65%~77%.The reaction process was readily monitored by conventional analytic way.It was easy in work-up.
