Adding a certain compound to certain chemical reactions, such as: 60010-03-9, 2,6-Dichloro-4-methyl-3-nitropyridine, 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, SDS of cas: 60010-03-9, blongs to pyridine-derivatives compound. SDS of cas: 60010-03-9
A suspension of 2,6-dichloro-4-methyl-3-nitropyridine (300 mg, 1.449 mmol) and sodium bicarbonate (243 mg, 2.90 mmol) in Tetrahydrofuran (THF) (20 mL)) was added (S)- dimethyl 2-aminosuccinate hydrochloride (430 mg, 2.174 mmol) at 0 C under nitrogen. Then the reaction mixture was stirred at 65 C for 24 hr. The reaction was monitored by TLC. The reaction mass filtered and washed with EtOAc (2 x 30 mL). The filtrate was concentrated under reduced pressure to give the crude material. The crude product was added to a neutral alumina column and was eluted with Hex/EtOAc (9: 1). Collected fractions were concentrated under reduced pressure to afford the desired product (250 mg, 0.742 mmol, 51.2 % yield) as yellow gummy liquid, LCMS (m/z) 339.1 (M+H)+.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,60010-03-9, 2,6-Dichloro-4-methyl-3-nitropyridine, and friends who are interested can also refer to it.
