Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 3196-15-4, name is Methyl 2-bromobutyrate, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 3196-15-4
DMF (3 mL) mixed solution of 5-chloro-4- (6-fluoro-2-mercaptobenzothiazole-5-yl) -1,2-tetramethylene-4-pyrazoline-3-one (240 mg, 0.67 mmol), cesium carbonate (264 mg, 1.2mmol) was stirred for 10 min, then 2-bromo-butyric acid methyl (107muL, 1.2mmol) was added and the mixture was stirred at room temperature for 24 hours. After the reaction, water was added to the reaction solution and extracted with chloroform. The organic layer was dried anhydrous magnesium sulfate and concentrated under reduced pressure. the obtained crude product was purified by eluting through silica gel column chromatography (ethyl acetate) to give a yellow oil of 2-[{5-(5-chloro-3-oxo-1,2-tetramethylene pyrazoline-4-yl)-6-fluoro-benzothiazol-2-yl} thio] methyl butanoate (171 mg, yield: 56%).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 3196-15-4.
