In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 160199-05-3, name is 2,4-Dichlorobenzo[4,5]thieno[3,2-d]pyrimidine, the common compound, a new synthetic route is introduced below. Product Details of 160199-05-3
2000 mL round bottom flask 25.0 g intermediate A ( 98.5 mmol ) , phenyl-3 – Boro Nick ester – carbazole 40.01 g (108.35 mmol, dealer : Beijing Green Technology Guardee) , potassium carbonate 34.04 g (246.26 mmol), Pd ( PPh3) 4(Tetrakis (triphenylphosphine)? Palladium (0)) 5.7 g (4.93 mmol) and 1,4- dioxane 600 mL , placed in 300 mL waterGave was then heated to reflux for 6 hours in a nitrogen stream . Inflicting a mixture obtained therefrom in 1500 mL of methanolAfter filtration over a solid crystallized , it was dissolved in monochlorobenzene , and filtered through a silica gel / Celite , an appropriate amount of an organic solventAfter removal , by re-crystallization with methanol to give the intermediate 16 – A ( 31.85 g , yield 70% ) .
The synthetic route of 160199-05-3 has been constantly updated, and we look forward to future research findings.
