Adding a certain compound to certain chemical reactions, such as: 13472-56-5, 2-Methoxy-5-methylpyridine, 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, Formula: C7H9NO, blongs to pyridine-derivatives compound. Formula: C7H9NO
n-BuLi (2.5 M, 1.95 mL) was added dropwise to a solution of 2-methoxy-5-methylpyridine (500 mg, 4.06 mmol) in THF (9 mL) at -78C and the mixture was stirred at -40C for 0.5 hours. A solution of triisopropyl borate (1.15 g, 6.09 mmol) in THF (1 mL) was added dropwise, and stirring continued for 0.5 hours at -78C.Then the reaction mixturre was stirred at 20C for an additional 12 hours. The reaction mixture was poured into water (10 mL) and stirred for 5 minutes.The aqueous phase was extracted with dichloromethane. The organic phase was washed with brine, dried over anhydrous Na2S04, filtered and concentrated in vacuo. The residue was purified by silica gel chromatography (petroleum ether/ethyl acetate) to afford the title compound.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,13472-56-5, 2-Methoxy-5-methylpyridine, and friends who are interested can also refer to it.
