Adding a certain compound to certain chemical reactions, such as: 1214336-41-0, Methyl 5-bromo-3-chloropicolinate, 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, name: Methyl 5-bromo-3-chloropicolinate, blongs to pyridine-derivatives compound. name: Methyl 5-bromo-3-chloropicolinate
[013381 NaBH4 (6 g, 158.52 mmol, 3.97 equiv) was added to a solution of methyl 5-bromo-3- chloropyridine-2-carboxylate (10 g, 39.92 mmol, 1.00 equiv) in methanol (150 mL) at 0C. The reaction was stirred for 3 h at 0C. The reaction was then quenched by water, diluted with ethyl acetate, washed with saturated sodium bicarbonate and brine, dried over anhydrous sodium sulfate, and concentrated under vacuum. This resulted in the title compound (8.9 g, crude) as a light yellow solid. LCMS [M+H] 224.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1214336-41-0, Methyl 5-bromo-3-chloropicolinate, and friends who are interested can also refer to it.
