Reference of 7397-62-8 ,Some common heterocyclic compound, 7397-62-8, molecular formula is C6H12O3, 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 II-a-1 CH3 SO2 OCH2 COO-nC4 H9 27.8 g (0.2 mol) of n-butyl hydroxyacetate (95% pure by GC) and 20.2 g (0.2 mol) of triethylamine are first introduced into 300 ml of dichloromethane at -5 C. 34.4 g (0.3 mol) of methanesulfonyl chloride in 50 ml of dichloromethane are slowly added dropwise at 0 to 5 C. Stirring of the batch at 0 C. is continued overnight, ice water is added, the phases are separated, and the aqueous phase is extracted twice with dichloromethane. The combined organic phases are dried, and the solvent is removed on a rotary evaporator leaving a colorless oil which is subjected to incipient distillation in vacuo. n-Butyl methylsulfonyloxyacetate is isolated as an almost colorless oil (40.5 g, 96.3% of theory, GC content 91%).
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. 7397-62-8, Butyl 2-hydroxyacetate, other downstream synthetic routes, hurry up and to see.
