Simple exploration of 3,5-Dichloropyrazine-2-carbonitrile

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.

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. 313339-92-3, name is 3,5-Dichloropyrazine-2-carbonitrile, A new synthetic method of this compound is introduced below., Formula: C5HCl2N3

To a cooled 0 C suspension of (3S,4S)-3-methyl-2-oxa-8-azaspiro[4.5]decan-4- amine dihydrochloride (4.19 g, 17.2 mmol) in acetonitrile (86 mL) were added Hunig’s base (15.06 mL, 86.0 mmol) and 3,5-dichloropyrazine-2-carbonitrile (3 g, 17.2 mmol). The resulting mixture was stirred at 25C for 1 h. The volatiles were removed under reduced pressure to give a yellow oil which was used without further purification. MS (ES+) C14H18C1N50 requires: 307, found: 308 [M+H] +.

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.
