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. 67832-11-5, name is 4-Bromo-2-methylbenzonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Formula: C8H6BrN
General procedure for coupling reaction: An oven-dried resealable Schlenk tube were charged with Pd(OAc)2 (6.7 mg, 0.03 mmol), Xantphos (34.7 mg, 0.06 mmol), 2-methylpropane-2-sulfinamide (145 mg, 1.2 mmol) and Cs2CO3 (650 mg, 2.0 mmol). The Schlenk tube was evacuated and back-filled with argon. 4-bromo-2-methylbenzonitrile (196 mg, 1.0 mmol) and dioxane (3 ml) were added and the Schlenk tube was then sealed with a Teflon screw cap and placed in a preheated oil bath at 100oC for 15 h. After cooling of the reaction mixture to room temperature, water was added and the reaction mixture was extracted with ethyl acetate. The combined organic layer was washed with brine, dried over Na2SO4, filtered, and concentrated under vacuum. The product was purified by flash chromatography. Yield: 228 mg, 97 % [table-1, entry-5].
The synthetic route of 67832-11-5 has been constantly updated, and we look forward to future research findings.
