These common heterocyclic compound, 3469-69-0, name is 4-Iodopyrazole, its 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. Computed Properties of C3H3IN2
Example 2: 4-((?)-2-(l-((2/?,3i?)-3-(2,4-Difluorophenyl)-3-hydroxy-4- (l/T-l,2,4-triazol-l-yl)butan-2-yl)-lflr-pyrazol-4-yl)vinyl)benzonitrileStep 1 : l-(l-Ethoxyethyl)-4-iodo-l//-pyrazole; 4-1OdO-IiZ-PyTaZoIe (3.Og) was suspended in benzene (15OmL) and the suspension was heated while stirring. Ethyl vinyl ether (4.4mL) was added thereto, concentrated HCl was added dropwise thereto, and the resulting mixture was stirred at 60 C for 3 hours. After completion of the reaction, the resulting mixture was concentrated by evaporation under a reduced pressure, and the residue was neutralized using aqueous saturated sodium hydrogen carbonate (1OmL). The resulting mixture was extracted
The synthetic route of 4-Iodopyrazole has been constantly updated, and we look forward to future research findings.
