Related Products of 108-50-9, These common heterocyclic compound, 108-50-9, name is 2,6-Dimethylpyrazine, 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.
EXAMPLE 107 alpha,alpha’-Dichloro-2,6-dimethylpyrazine A stirred mixture of 2,6-dimethylpyrazine (55 mmol), N-chlorosuccinimide (110 mmol) and benzoylperoxide (1.0 mmol) in carbon tetrachloride (150 mL) is heated to reflux under nitrogen for 30 hours. Additional N-chlorosuccinimide (140 mmol) and benzoylperoxide (2.3 mmol) are added at 6 hours. The cooled reaction mixture is filtered and the filtrate washed with sodium carbonate (saturated aqueous solution) and dried. Evaporation of the solvent gives the title compound.
The synthetic route of 108-50-9 has been constantly updated, and we look forward to future research findings.
