Adding a certain compound to certain chemical reactions, such as: 1384973-12-9, name is 5-Amino-3-bromo-1H-pyrazole-4-carbonitrile, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 1384973-12-9, Quality Control of 5-Amino-3-bromo-1H-pyrazole-4-carbonitrile
A mixture of 5-amino-3-bromo-1H-pyrazole-4-carbonitrile 7b (10 g, 53.8 mmol), 3-(toluenesulfonyloxy)pyrrolidine-1-carboxylic acid tert-butyl ester (22 g, 64.5 mmol), cesium carbonate (58 g, 107.6 mmol) and acetonitrile (250 mL) was heated to 90 C. and reacted for 4 hours, and was then cooled to room temperature, filtered and the resulting filter cake was washed with dichloromethane, the filtrates were combined and concentrated under reduced pressure, the residue was purified by silica gel column chromatography (petroleum ether/ethyl acetate=5/1), so as to obtain the title product (S)-3-(5-amino-3-bromo-4-cyano-1H-pyrazol-1-yl)pyrrolidine-1-carboxylic acid tert-butyl ester 7c (5 g, yellow oil), and the yield was 26%. MS m/z (ESI): 300/302[M+1-56]
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, 5-Amino-3-bromo-1H-pyrazole-4-carbonitrile, other downstream synthetic routes, hurry up and to see.
