Pyrimidine derivatives are very important molecules in biology and are widely used in the areas of pesticide, such as imazosulfuron, ethirmol and mepanipyrim [1-4]. Particularly in the late 1990s, pyrimidyl (thio)-oxybenzoate, classisfied as acetolactate synthase inhibitors, were found to exhibit high selectivity and herbicidal activity at very low rates of application and Pyrithiobacsodium is one of the representatives [5-7]. Since the discovery of ...
