The invention provides 1,2,4-triazole compounds, compositions containing those compounds, methods of treating diseases and/or disorders with those compounds and processes of manufacturing 1,2,4-triazole compounds.
We report a new method using silver benzoate instead of mercury salts as a key reagent for the synthesis of 3,4,5-trisubstituted 1,2,4-triazoles. This method allows the introduction of a large variety of substituents in the three positions. We demonstrated that we could introduce one chiral center without any loss of the optical purity. This method is compatible with at least multi-gram scale-up. (C) 2010 Elsevier Ltd. All rights reserved.
