Synthesis of p-anisyl-urea.

 

Statement :

the reaction of p-nitrophenol with di-methyl sulphonate [(CH₃)₂SO₄] in the presence of NaOH, gives       p-methoxy-nitrobenzene.  After that the reduction of p-methoxy-nitrobenzene in the presence of metal [Sn] and HCl gives p-methoxy-aniline. Then the reaction of p-methoxy-aniline with urea [NH₂-CO-NH₂] yields p-anisyl-urea.  

 

Chemical reaction :

 

Uses of p-anisyl-urea

p-anisyl-urea is used as a sweeteners in the place of sugars.
