Synthetic Route of 17626-40-3, These common heterocyclic compound, 17626-40-3, name is 3,4-Diaminobenzonitrile, 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.
General procedure: To a stirred solution of alkyne (0.2 mmol) in DMSO (2.0 mL) was added I2 (10.1 mg, 0.04 mmol). The solution was stirred at 130 oC for 24 h in air. Then the mixture was cooled to room temperature, and o-Phenylenediamine (0.3 mmol) was added. The solution was stirred at room temperature for 1 h. After completion, the solution was diluted with ethyl acetate, washed with H2O, dried over MgSO4, and concentrated in vacuo. The residue was purified by preparative thin-layer chromatography on silica gel with PE/EtOAc (15/1) as an eluent to give quinoxaline 3.
Statistics shows that 3,4-Diaminobenzonitrile is playing an increasingly important role. we look forward to future research findings about 17626-40-3.
