Application of 1613191-73-3, The chemical industry reduces the impact on the environment during synthesis 1613191-73-3, name is Allyl 3,5-diamino-1H-pyrazole-4-carboxylate, I believe this compound will play a more active role in future production and life.
[0450] To a suspension ofallyl3,5-diamino-1H-pyrazole-4-carboxylate 3 ( 42.72 g, 234.5 mmol) in DMSO (270.8mL)/Water(270.8 mL), was added p-TsOHhydrate (46.72 g,245.6 mmol) and 3-( diisopropylamino )-2-fluoro-prop-2-enal(described in Tetrahedron Letters, 33(3), 357-60; 1992) (38.69 g, 223.3 mmol). The reaction mixture was heated to 100C. for 3 hr. during which time a solid slowly precipitated outof solution. The orange suspension was allowed to cool downto RT overnight. The solid was filtered, washed with waterand dried under vacuum to give allyl2-amino-6-fluoro-pyrazolo[1,5-a]pyrimidine-3-carboxylate 4a as a sand solid (45.05 g, 85% yield).
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, Allyl 3,5-diamino-1H-pyrazole-4-carboxylate, other downstream synthetic routes, hurry up and to see.
