31827-94-8, name is 2-Bromo-1-(4-iodophenyl)ethanone, 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. category: iodides-buliding-blocks
General procedure: The appropriate carbonyl compound (50 mmol) was dissolved in 50 mL of ethanol and magnetically stirred with an equimolar quantity of thiosemicarbazide for 24 h at room temperature with catalytic amounts of acetic acid. The desired thiosemicarbazone precipitated from reaction mixture, was filtered, crystallized from suitable solvent, and dried. Equimolar quantities of 4-iodo-acetophenone and bromine, both dissolved in chloroform, were stirred for 4 h at room temperature until the presence of HBr disappeared. The solution was evaporated under vacuum and the obtained pale yellow solid was washed with petroleum ether to give alpha-bromo-4-iodo-acetophenone in good yield (94%). Equimolar amounts of the prepared thiosemicarbazone (50 mmol) and alpha-bromo-4-iodo-acetophenone (50 mmol), both suspended in 50 mL of ethanol, were reacted at room temperature under magnetic stirring for 10 h. The precipitate was filtered and purified by chromatography to give compounds 1-25 in high yield.
The synthetic route of 31827-94-8 has been constantly updated, and we look forward to future research findings.
