Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 287922-71-8, name is 4-Bromo-1-methyl-1H-pyrazole-3-carbonitrile, A new synthetic method of this compound is introduced below., category: pyrazoles-derivatives<\/a><\/p>\n

a) 500 mg (2.69 mmol) 4-Bromo-1-methyl-1H-pyrazole-3-carbonitrile, 1.21 mg (5.00 muMol) Pd(OAc)2, 44.7 mg (0.08 mmol) dppf and 661 mg (8.06 mmol) NaOAc are added to 20 mL MeOH and stirred in an atmosphere of CO (p=10 bar) at 120 C. over night. Then the solvent is removed and the residue is purified by HPLC (MeOH\/H2O\/TFA).<\/p>\n

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.<\/p>\n
