Adding a certain compound to certain chemical reactions, such as: 5445-17-0, name is Methyl 2-bromopropanoate, belongs to esters-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 5445-17-0, Recommanded Product: Methyl 2-bromopropanoate
A solution of 1-(5-trifluoromethyl-pyridin-2-yl)-piperazine (0.9 g, 3.9 mmoles) in MeOH (13 mL) and DIPEA (1.5 mL) was treated with 2-bromo-propionic acid methyl ester (0.48 mL, 4.3 mmoles) and stirred overnight at 70 C. MeOH was removed under reduced pressure and the residue was purified (silica gel, 10-40% acetone in hexane) to provide the title compound as a yellowish solid (1.23 g, 99%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Methyl 2-bromopropanoate, and friends who are interested can also refer to it.
