One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: pyrrolines, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 119018-29-0, Name is 4-[2-[(3-Ethyl-4-methyl-2-oxo-3-pyrrolin-1-yl)carboxamido]ethyl]benzenesulfonamide, molecular formula is C16H21N3O4S
A preparation method of glimepiride (by machine translation)
The invention discloses a method for preparing for glimepiride, which belongs to the technical field of the synthesized compounds. The invention through N, N’ – carbonyl imidazole as the condensing agent, in order to compound I: N – 4 – [2 – (3 – ethyl – 4 – methyl – 2 – oxo – 3 – pyrroline – 1 – carboxamido) ethyl] – benzene sulfonamide and compound II: trans 4 – methyl cyclohexyl amine as the starting material, by condensation reaction, through simple purification processing, can get the glimepiride. Compared with the existing method, the method avoids the use of toxic of the triphosgene or phosgene, while avoiding preparation isocyanate or carbamate intermediate of the increase of the process route, the method has simple technique, the procedure is short, simple operation and the like.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: pyrrolines, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 119018-29-0, in my other articles.
