Synthetic Route of 2058-72-2, A common heterocyclic compound, 2058-72-2, name is 5-Bromo-1-methylindoline-2,3-dione, molecular formula is C9H6BrNO2, 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.
The key intermediate 2 was refluxed with equivalent amount ofdifferent isatin derivatives 4a-f or 8a-l in glacial acetic acid. Thereaction was monitored with TLC. After complete of the reaction,the formed solid was collected and washed with water andrecrystallized from DMF/ethanol to get the target compounds 6a-fand 9a-l respectively.
The synthetic route of 2058-72-2 has been constantly updated, and we look forward to future research findings.
