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. 588-96-5, name is p-Bromophenetole, A new synthetic method of this compound is introduced below., Recommanded Product: p-Bromophenetole

(1) A small amount of iodine was added to a suspension of 1-bromo-4-ethoxybenzene (484 muL) and magnesium (82.3 mg) in THF at room temperature in a nitrogen atmosphere, and the mixture was stirred at 50 C. for one hour. The reaction solution was returned to room temperature and a solution of 5-cyclopropyl-6-methoxypyridine-2-carbaldehyde (300 mg) in tetrahydrofuran (1 mL) was added, followed by stirring at 50 C. for one hour. Tetrahydrofuran was concentrated under reduced pressure and a saturated ammonium chloride solution was added, followed by extraction with ethyl acetate. The organic layer was filtered through diatomaceous earth, and then the solvent was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=50:1?9:1) to give (5-cyclopropyl-6-methoxypyridin-2-yl)(4-ethoxyphenyl)methanol as a yellow oil (438 mg, 86%).

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.

588-96-5, A common heterocyclic compound, 588-96-5, name is p-Bromophenetole, molecular formula is C8H9BrO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

General procedure: b.Cyanation of aryl bromides. To a solution of arylbromide (0.5 mmol) in EtOH (5.0 mL) was added NCTS (272 mg, 1.0 mmol), PdCl2 (13.3 mg, 0.075 mmol), and Ag2O (57.75 mg, 0.5 mmol). The mixture was stirred at 70 for 24 hunder air atmosphere. Then the reaction mixture was cooled to room temperature and filtered through a pad of celite (1.0 g) and rinsed with CH2Cl2 (10.0 mL). The resulting organic solution was concentrated under reduced pressure and further purified by flash chromatography (SiO2,petroleum ether/EtOAc gradient), yielding the corresponding aryl nitriles.

The synthetic route of p-Bromophenetole has been constantly updated, and we look forward to future research findings.
