Electric Literature of 33332-25-1, The chemical industry reduces the impact on the environment during synthesis 33332-25-1, name is Methyl 5-chloropyrazine-2-carboxylate, I believe this compound will play a more active role in future production and life.
Intermediate 57A mixture of methyl 5-chloropyrazine-2-carboxylate (0.75 g), K2CO3 (1 .8 g) and 1 H- 1 ,2,4-triazole (1 .2 g) in N,N-dimethylformamide (6 mL) is heated to 100 C overnight. Analysis of the crude mixture by LCMS shows saponified product. The product is acidified with 1 N HCI and the precipitate is filtered and washed with water and diethyl ether to afford the title compound. LC (method 20): tR = 1 .06 min; Mass spectrum (APCI): m/z = 192 [M+H]+.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Methyl 5-chloropyrazine-2-carboxylate, other downstream synthetic routes, hurry up and to see.
