General Description

The Suzuki coupling of 4-bromo-2-nitrophenol with boronic acid was studied.

Synthesis

The synthesis method of 4-bromo-2-nitrophenol comprises the following steps: preparing nitric acid with a concentration of 7-8 M; dissolving p-bromophenol in dichloroethane to obtain a substrate with a concentration of 1.8-2.2 M; injecting the nitric acid and the substrate into a continuous flow reactor through two pumps respectively, mixing, controlling the temperature at 55-75°C, the reaction pressure at 0.35-0.45 MPa, and reacting for 20-30 min.
