Paragraph 0041-0048, (2020/05/14)
The invention relates to a synthesis method of a 2-aryl benzotriazole compound. In an organic solvent, under a nitrogen condition, an o-phenylenediamine compound with a structure shown as a formula (I) in the structural formula and an aryl nitrogen source with a structure shown as a formula (II) in the structural formula are used as reaction substrates to be successively subjected to intermolecular N-N coupling and intramolecular N-N bond coupling condensation by using a cheap copper-containing catalyst in a strong alkali environment so as to obtain a 2-aryl benzotriazole compound. According to the method, o-phenylenediamine and nitrobenzene raw materials are commercialized, cheap and easily available, the reaction substrate range is wide, the functional group tolerance is good, the reaction conditions are simple, the yield and purity of the product are high, a new synthesis route and a method are developed for the 2-aryl benzotriazole compound, and the method has good application potential and research value.

Reported is the condensation between o-arylenediamines and nitroarenes enabled by a cooperative action of acid and base, providing a direct entry to 2-aryl-2H-benzotriazoles. The potential practicability of this methodology was demonstrated by 100 mmol-scale reactions and the synthesis of serotonin/dopamine receptor ligand and human growth hormone. (Figure presented.).
