Adding a certain compound to certain chemical reactions, such as: 1379338-74-5, name is 5,7-Dichloropyrido[3,4-b]pyrazine, belongs to pyrazines 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 1379338-74-5, Recommanded Product: 1379338-74-5
E) terf-butyl 3-(tert-butyldi methylsilyloxy)-5-((7-chloropyrido[4,3-ib]pyrazi n-5- ylami no)methyl)piperidi ne-1 -carboxylate.[01 13] A solution of terf-butyl 3-(aminomethyl)-5-(ieri-butyldimethylsilyloxy)piperidine- 1 -carboxylate (4.74 g, 13.7 mmol), 5,7-dichloropyrido[4,3-£>]pyrazine (2.75 g, 13.7 mmol) and DIPEA (2.12 g, 16.4 mmol) in THF (20 mL) was stirred at roomtemperature for 48 hours. The volatiles were removed under reduced pressure and the residue was treated with ethyl acetate, washed with brine, dried over Na2SO4, filtered, and concentrated to give the title compound.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 5,7-Dichloropyrido[3,4-b]pyrazine, and friends who are interested can also refer to it.
