Application of 119018-29-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 119018-29-0, 4-[2-[(3-Ethyl-4-methyl-2-oxo-3-pyrrolin-1-yl)carboxamido]ethyl]benzenesulfonamide, introducing its new discovery.
Blood sugar lowering medicine glimepiride preparation method (by machine translation)
The invention discloses hypoglycemic drug glimepiride preparation method, the effects of offering a blood sugar drug glimepiride chemical name 1 – [4 – [2 – (3 – ethyl – 4 – methyl – 2 – oxo – 3 – pyrroline – 1 – carboxamido) – ethyl] – benzene sulfonyl] – 3 – (trans – 4 – methyl cyclohexyl) – urea, its chemical formula is C24 H34 N4 O5 S, its structural formula is: ; The process of the invention is simple, short synthetic route, high yield, in particular 2 – (3 – ethyl – 4 – methyl – 2 – oxo – 3 – pyrroline – 1 – carboxamido) ethyl benzene sulfonic acid yield is greatly improved, the sulfonation using chlorosulfonic acid had a significant impact on effect, compared to the prior art of the sulfonating agent used in concentrated sulfuric acid, fuming sulfuric acid and the like sulfonated capacity is stronger, it is easy to further produce the glimepiride, raw materials are easy, economic and environmental protection, product yield and high purity of the product, favorable to the industrialized.
