Electric Literature of 32692-19-6, These common heterocyclic compound, 32692-19-6, name is 5-Nitroindoline, 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.
7-Bromo-5-nitroindoline To a solution of 5-nitroindoline (from Aldrich, 2.0 g, 12.2 mmol) in 15 mL of AcOH was added Br2 (1.0 mL, 19.4 mmol) in a portion and the resulting solution was stirred for 1 h at 25 C. Reaction mixture was concentrated in vacuo, yielding a yellow solid (3.9 g, >95%) of the desired product as a HBr salt, which was subjected to the following reaction without further purification.
The synthetic route of 32692-19-6 has been constantly updated, and we look forward to future research findings.
