Abstract:Dimethoxy-2-methylsulfonylpyrimidine is an important intermediate for pesticide, especially for the preparation of 2-(2′-pyrimidyloxy)-N-het/aryl-benzylamine derivatives, a class of green novel herbicide. It was synthesized using sulphur urea and diethyl malonate as raw materials with yield of 62.3%. The process is simple and viable. |
