Adding a certain compound to certain chemical reactions, such as: 288246-16-2, name is 4-Bromo-1H-pyrazole-5-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 288246-16-2, HPLC of Formula: C4H2BrN3<\/a><\/p>\n

To a solution of 4-bromo-3-cyano-lH-pyrazole 49 (172 mg, 1 mmol) in pyridine (3 mL) was added 2,5-difluorophenyl boronic acid (237 mg, 1.5 mmol), and 4A molecular sieves. The mixture was stirred for 72 h at room temperature. The reaction was worked-up with saturated NaHC0 and EtOAc extraction. The organic layer was separated and aqueous was extracted with EtOAc. The combined organic phase was dried over a2S04, filtered, and concentrated to give crude product. The crude product was purified on ISCO columns. Fractions containing pure product were combined and evaporated to give 50 (70 mg, 25%) as a blue wax.<\/p>\n

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, 4-Bromo-1H-pyrazole-5-carbonitrile, other downstream synthetic routes, hurry up and to see.<\/p>\n","protected":false},"excerpt":{"rendered":"
