Related Products of 2075-45-8<\/a>,Some common heterocyclic compound, 2075-45-8, name is 4-Bromo-1H-pyrazole, molecular formula is C3H3BrN2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

A sealable vessel was charged with potassium carbonate (3.76 g, 27.2 mmol), 4-bromo- lH-pyrazole (4.00 g, 27.2 mmol), and 10 mL DMF. To this mixture, 2-iodopropane (3.27 ml, 32.7 mmol) was added and the vessel sealed. The mixture was heated at 80 C for 16 h and allowed to cool to rt . The mixture was diluted with EtOAc, extracted with water, water, sat NaHCO3, and the organic layer dried over Na2SO4, filtered and evaporated. The mixture was purified via flash chromatography using a EtOAc in CH2C12 gradient. The desired compound (as determined by TLC, 12 stain) was collected as a colorless liquid.<\/p>\n

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-Bromo-1H-pyrazole, its application will become more common.<\/p>\n
