Adding a certain compound to certain chemical reactions, such as: 67832-11-5, name is 4-Bromo-2-methylbenzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 67832-11-5, Recommanded Product: 67832-11-5
Methyl magnesium bromide (3 M in tetrahydrofuran) was added at rt drop wise to a solution of 4-bromo-2-methylbenzonitrile (4 g) in dry THF (15 mL) and was then heated to reflux for 2 h and then stirred at rt for 3 d. The mixture was chilled in an ice bath, saturated aqueous ammonium chloride solution (100 mL) was added and the mixture was extracted with EtOAc. The combined organic layers were concentrated under reduced pressure and the remaining residue was treated with 4 N HCl at 0 C. and was stirred at rt for 18 h. The mixture was extracted with EtOAc and the organic layer was washed with water, dried and the solvent was removed under reduced pressure to yield the desired product (88% yield).
