Synthesis of a 5-((Aryloxy)methyl)-3-(4-(trifluoromethyl)phenyl)[1,2,4]thiadiazole Derivative: A Promising PPARα,δ Agonist

SUZUKI-MIYAURA COUPLING REACTIONS OF 3,5-DICHLORO-1,2,4-THIADIAZOLE

3,5-Dichloro-1,2,4-thiadiazole was allowed to react with different arylboronic acids under different Suzuki-Miyaura coupling conditions: at room temperature 5-aryl-3-chloro-1,2,4-thiadiazoles were obtained and at toluene reflux temperature the products were 3,5-diaryl-1,2,4-thiadiazoles. Sequential coupling reactions lead to 3,5-diaryl-1,2,4-thiadiazoles with non-identical aryl groups. The structure of 3-methoxy-5-(4-methoxyphenyl)-1,2,4-thiadiazole was established from X-ray crystallographic data.
