Application of 79491-46-6 ,Some common heterocyclic compound, 79491-46-6, molecular formula is C6H4Br2N2O3, 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.
To a solution of Compound 138 (200 mg, 0.64 mmol) in anhyd MeOH (6 mL) was added NaOMe (46 mg, 0.85 mmol). The reaction mixture was stirred at room temperature for 1 h and then concentrated under vacuum. The resulting residue was washed with water and filtered. The collected solids were washed with ice cold water and dried under vacuum to give Compound 139 (150 mg, 89% yield).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 79491-46-6, 2,6-Dibromo-3-methoxy-5-nitropyridine, other downstream synthetic routes, hurry up and to see.
