1117-71-1, name is Methyl 4-bromobut-2-enoate, belongs to esters-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. Quality Control of Methyl 4-bromobut-2-enoate
To the suspension of potassium phthalimide (4.5 mmol) in dry DMF (4 mL) was added a solution of (E)-alkyl -bromobut-2-enoate in dry DMF (3 mL). The reaction was run at room temperature overnight. After the reaction was omplete, the reaction mixture was poured into water and extracted with ether and concentrated in vacuum to leave a hite solid. The residue can be easily purified by flash chromatography (petroleum/ethyl acetate, 4:1), to give the desired compounds 1.
The synthetic route of 1117-71-1 has been constantly updated, and we look forward to future research findings.
