Novel aryl-1,2,4-triazolo[1,5-a]pyrimidines (3-23) were prepared in good yields from corresponding 3-amino-1,2,4-triazoles by employing Doebner-Miller reaction. In some reactions intermediate dihydro products (3, 7, 17, 19, 23) were also isolated and identified. These compounds showed only mild antibacterial activity.
