Description
Synthesis Analysis
A general method for the preparation of bis-ureas from bis(o-nitrophenyl) carbonate involves directional urea synthesis by sequential amine addition. Initially, bis(o-nitrophenyl) carbonate reacts with benzylamine to form benzyl-o-nitrophenyl carbamate; subsequently, the carbamate reacts with diamines in toluene to yield bis-ureas
