4387-36-4, name is 2-Iodobenzonitrile, belongs to iodides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Computed Properties of C7H4IN
S1: The reaction formula of this step is as follows.The specific reaction operation is: at room temperature,Adding 100 mmol of the compound of the above formula (III) to an appropriate amount of the organic solvent N,N-dimethylacetamide (DMA),175 mmol of the above compound of formula (IV), 0.6 mmol of palladium acetate,125 mmol of tetra-n-butylammonium bromide and 175 mmol of sodium carbonate, and then the temperature was raised to 110 C with stirring.And stirring the reaction at this temperature for 20 hours;After the reaction was completed, the reaction mixture was poured into a sufficient amount of ethyl acetate.After washing with saturated brine, the organic layer and the aqueous layer were separated.After the aqueous layer is sufficiently extracted with ethyl acetate,The organic layers are combined (ie, the organic layer washed with saturated brine and the organic layer obtained by ethyl acetate extraction).Dry with anhydrous Na2SO4 and distill under reduced pressure.The residue was eluted by flash column chromatography (a mixture of petroleum ether and ethyl acetate in a volume ratio of 8:1).The eluent was collected and evaporated to remove the eluent.Thus obtaining a compound of the above formula (II) as a white solid in a yield of 88.2%
The synthetic route of 4387-36-4 has been constantly updated, and we look forward to future research findings.
