The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 183438-24-6, name is 5-Bromo-2-iodopyrimidine. This compound has unique chemical properties. The synthetic route is as follows. Product Details of 183438-24-6

First of all, 5-bromo-2-iodopyrimidine 1.97g and phenyl boronic acid 0.85g, 2M sodium carbonate aqueous solution 7.0mL, toluene 18mL, reflux condenser put in a 200mL three-necked flask equipped with a, in the flask was replaced with nitrogen. After degassing with stirring under reduced pressure, tetrakis (triphenylphosphine) palladium (0) (abbreviation: Pd (PPh 3 ) 4 ) 0.081 g and the mixture was refluxed for 8 hours. Here, Pd (PPh 3 ) 4 0.040 g was added, and the mixture was refluxed for 8 hours, more Pd (PPh 3 ) 4 0.040 g was added and reacted by refluxing for 8 hours. Water was added to the reaction solution, and the organic layer was extracted with dichloromethane. The resulting extract was washed with saturated brine, and dried over magnesium sulfate. After the drying, the solution was filtered. After evaporating the solvent of this solution, the resulting residue, hexane: ethyl acetate = 5: 1 was purified by flash column chromatography as a developing solvent, to give a pyrimidine derivative of interest (white powder, yield: 59percent).

With the rapid development of chemical substances, we look forward to future research findings about 183438-24-6.
