Application of 2503-56-2 ,Some common heterocyclic compound, 2503-56-2, molecular formula is C6H6N4O, 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.
[0171] Compounds 4c. 5-Methyl-pyrazolo[l,5-alpha]pyrimidin-7-ol/7-Methyl-imidazo[l,2- alpha]pyrimidin-5-ol/5-Methyl-[l,2,4]triazolo[l,5-alpha]-pyrimidin-7-ol (3c) (6.5 mmol) was added to 1.82 ml (19.5 mmol) of phosphorus oxychloride and heated under reflux for 30-60 minutes, in a round bottom flask, during which time the solid dissolved and hydrogen chloride was evolved. Excess phosphorus oxychloride was removed by distillation at reduced
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. 2503-56-2, 7-Hydroxy-5-methyl-1,3,4-triazaindolizine, other downstream synthetic routes, hurry up and to see.
