Based on high performance liquid chromatography (HPLC), a fast, efficient and simple route for Smiles rearrangement reaction has been developed in the presence of 2-pyrimidinyloxy-N-arylbenzylamine derivatives as reactants with HCl as acid catalyst in mixed CH3OH/H2O medium at room temperature. The advantage of the proposed method is that the products with excellent yields and high purity can be obtained employing reused solvent without further separating process. Considering the cheapness of catalyst and solvent, as well as high efficient and environment-friendly reaction condition, the developed method has the practicability and environmentally friendliness.
