Adding a certain compound to certain chemical reactions, such as: 89809-63-2, 5-Methoxypicolinonitrile, 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, 89809-63-2, blongs to pyridine-derivatives compound. Safety of 5-Methoxypicolinonitrile
General procedure: To a solution of diisopropylamine (170 muL, 1.2 eq.) in dry THF (2 mL) in a flame dried round bottom flask under argon at 0 C was added n-butyllithium (690 muL, 1.6 M in hexanes, 1.1 eq.), and the reaction mixture was stirred at this temperature for 15 minutes. It was then cooled to -78 C and a solution of ketone (1) (1 mmol) in THF (2 mL) slowly added. Stirring at -78 C was continued for a further 30 minutes and methyl chlorosulfate (100 muL, 1.1 eq.) was then added. After stirring at -78 C for 30 minutes, the reaction was quenched with an aqueous saturated ammonium chloride solution (5 mL). The mixture was then extracted with dichloromethane (3 x 5 mL), the combined organic phases were dried with anhydrous magnesium sulfate and the solvent evaporated under vacuum affording the desired alpha-chloroketone 2.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,89809-63-2, its application will become more common.
