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. 23426-63-3, name is Methyl 2-bromo-2-methylpropanoate, This compound has unique chemical properties. The synthetic route is as follows., Formula: C5H9BrO2
Step B; 2,5-Dimethyl-4-thiocyanato-phenol 72 (5.75 g, 32.1 mmol) is dissolved in acetonitrile (25 mL). Powdered cesium carbonate (15.32 g, 47.0 mmol) is added. Then 2- bromo-2-methyl-propionic acid methyl ester (4.50 mL, 34.8 mmol) is added and the mixture is stirred at 6O0C for 18 h. Filtration and concentration, followed by silica gel chromatography (0-50% ethyl acetate in hexanes) yielded 2-(2,5-dimethyl-4-thiocyanato- phenoxy)-2-methyl-propionic acid methyl ester 73 as an oil: 1H-NMR (400 MHz, CDCb) (rotamers are present; the data given is for the most abundant isomer) delta = 7.39 (s, IH), 6.50
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 23426-63-3.
