Sources of common compounds: 5-Chloro-2,3-diphenylpyrazine

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

41270-66-0, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 41270-66-0, name is 5-Chloro-2,3-diphenylpyrazine, A new synthetic method of this compound is introduced below.

2-chloro-5,6-diphenylpyrazine (10 gm), 4-(isopropylamino)-1 -butanol (44 gm) and N-methylpyrrolidine (50 mL) were charged into a 250 mL round bottom flask at 30C. The reaction mass was heated to 190C and stirred for 10 hours. The reaction mass was cooled to 30C and poured into cold water, extracted with ethylacetate, dried over anhydrous magnesium sulphate and then concentrated to get 9 gm of the title compound.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
