Reference of 1379338-74-5, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1379338-74-5, name is 5,7-Dichloropyrido[3,4-b]pyrazine, This compound has unique chemical properties. The synthetic route is as follows.
A solution of tert-butyl 3-(aminomethyl)-5-(tert-butyldimethylsilyloxy)piperidine-1-carboxylate (4.74 g, 13.7 mmol), 5,7-dichloropyrido[4,3-b]pyrazine (2.75 g, 13.7 mmol) and DIPEA (2.12 g, 16.4 mmol) in THF (20 mL) was stirred at room temperature 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.
The chemical industry reduces the impact on the environment during synthesis 5,7-Dichloropyrido[3,4-b]pyrazine. I believe this compound will play a more active role in future production and life.
