Related Products of 54608-52-5, The chemical industry reduces the impact on the environment during synthesis 54608-52-5, name is 2-Hydrazinopyrazine, I believe this compound will play a more active role in future production and life.
Example-4: Preparation of Selinexor (0507) (0508) (Z)-3-(3-(3,5-bis(trifluoromethyl)phenyl)-1 H-1 ,2,4-triazol-1 -yl)acrylic acid (10 g) was combined with a mixture of acetonitrile (1 00 mL) and ethyl acetate (50 mL) then added the 2-hydrazinylpyrazine (3.76 g) and stirred for 5 min. Reaction mixture was cooled to 0C and diisopropyl ethyl amine (16.63 ml) and then Propylphosphonic anhydride (T3P, 33.31 mL) was added at 0C and stirred the reaction mixture for 2.5 hours at the same temperature. After completion of the reaction, the reaction mixture was quenched with cold water (100 mL) and extracted the product with ethyl acetate (2 x 150 mL). The combined organic layer was dried over sodium sulphate and evaporated the solvent under vacuum at 40C to obtain the crude product as yellow syrup. The obtained crude product was combined with dichloromethane (1 00 mL) and filtered the solid and washed with dichloromethane (2 x 50 mL). The solid was dried under vacuum at 40C to obtain the title compound with purity by HPLC of 99.86%. Yield : 7 g
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, 2-Hydrazinopyrazine, other downstream synthetic routes, hurry up and to see.
