866837-96-9, name is Ethyl 5-amino-1-phenyl-1H-pyrazole-3-carboxylate, belongs to pyrazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Safety of Ethyl 5-amino-1-phenyl-1H-pyrazole-3-carboxylate<\/a><\/p>\n

11512] A solution of ethyl 5-amino-i-phenyl-1H-pyra-zole-3-carboxylate (CAS: 866837-96-9, 300 mg, 1.3 mmol) in THF (6.5 mE), under nitrogen atmosphere was cooled down to -78 C. Diisobutylaluminum hydride (1 M in toluene, 2.9 mE, 2.9 mmol) was added dropwise to the solution, and the stirring at -78 C. was continued for 1 hour. Methanol was added, and the reaction mixture was stirred for 30 minutes warming to RT. DCM was added, and the organic phase was washed with water. The organic phase was separated using a phase separator and concentrated under reduced pressure. The titled compound was used as such without any further purification.<\/p>\n

The synthetic route of 866837-96-9 has been constantly updated, and we look forward to future research findings.<\/p>\n
