Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 6911-87-1, name is 4-Bromo-N-methylaniline, A new synthetic method of this compound is introduced below., HPLC of Formula: C7H8BrN
To a microwave reaction vessel were added 2-aminopyridine-5-boronic acid pinacol ester (220 mg, 1.0 mmol), 4-bromo-N-methylaniline (184 mg, 1.0 mmol), 1,4-dioxane (4 mL) and 20% aq sodium carbonate (3 mL). Argon gas was bubbled through the solution for 5 min, then tetrakis(triphenylphosphine) palladium(O) (57 mg, 0.05 mmol) was added. The vial was sealed and heated in a microwave reactor for 30 min at 150 C. After cooling to rt, silica gel was added and the mixture was concentrated under reduced pressure. Purification by silica gel flash chromatography eluting with 1 :20 MeOH/ EtOAc gave 5-(4-
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
