1. I will not upload pictures, probably talking about me, acid first with the DPPA, obtain a molecule of phenol, and intermediate (phosphate), the ester bond in the post-intermediate is broken to obtain an acyllabis nitride, andPenyl Phosphenate,
2. The obtained acyl nitrogen was rearranged to obtain nitrogen and isocyanate, and then the isocyanate having no complete hydrolyzed isocyanate and the product amide will react to the urea.
