摘要:
The present invention relates to a novel method for the preparation of a key intermediate pyridine compound for producing fluoroalkylpyridine sulfonyl urea derivatives showing superior herbicidal activity novel alkylthioolefin derivatives used in the preparation and a method for the preparation thereof. According to the present method using the novel alkylthioolefin derivatives of Formula 2 the intermediate compound of Formula 1 for producing flucetosulfuron can be prepared through a simple processing step with a yield equivalent or superior to those of conventional methods.
