Application of 4270-27-3 ,Some common heterocyclic compound, 4270-27-3, molecular formula is C4H3ClN2O2, 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: 6-Chloropyrimidine-2,4(1H, 3H)-dione derivatives 1 (1.0 mmol) and N-hydroxyformimidoyl chloride derivatives 2 (1.2 mmol) were combined and dissolved in methanol (15mL), followed by the addition of triethylamine (3.0 mmol). Subsequently, the reaction mixture was stirred in a round-bottom flask (25mL) at room temperature for 5h. After completion of the reaction as indicated by TLC, the mixture was evaporated by rotary evaporator, extracted with ethyl acetate, dried over Na2SO4, then concentrated and purified by flash column chromatography (PE/EA=5:1) to yield compounds 3a-t.
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. 4270-27-3, 6-Chloropyrimidine-2,4(1H,3H)-dione, other downstream synthetic routes, hurry up and to see.
