Reaction Steps
The urea was synthesized by the treatment of 2-phenoxyphenyl carboxylic acid(2 mmol,) with diphenyl phosphoryl azide (0.475 mL) and triethyl amine (14 mL) in DMF at 80° C. after 24 hours the 2-amino 5-nitro phenol (I equiv.) was added. The reaction was heated for 24 hours at 80° C. The reaction product was oiled out with hexane. The residue was dissolved in methanol and the solid was precipitated out with water.(180 mg, 24%) EI-MS m/z 364 (M−H)−
