In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 3268-21-1 as follows. Product Details of 3268-21-1
(Step 3) Synthesis of Compound 169; [0096] After 250 mg of 1,4-diiodo-2,3,5,6-tetramethylbenzene (d) (0.648 mmol) was dissolved in 3 ml of 1,2-dimethoxyethane, 0.5 ml of ethanol and 0.5 ml of water were added to the solution. To the solution, 537 mg of potassium carbonate (3.89 mmol) and 350 mg of Boric acid compound (c) (1.943 mmol) were added and 37.4 mg of tetrakis(triphenylphosphine)palladium (0) (0.324 mmol) was added under argon atmosphere. The suspension was refluxed overnight under argon atmosphere. After cooling, water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, successively, dried and concentrated. The residue was recrystallized from methanol to obtain Compound 169 (213 mg; 82% yield).
According to the analysis of related databases, 3268-21-1, the application of this compound in the production field has become more and more popular.
