Methyl 1,4-Benzodioxan-6-carboxylate, cas is 20197-75-5, it is a common heterocyclic compound, the benzodioxans compound, its synthesis route is as follows.
A stirred solution of compound 3 (0.1 mol) in ethanol (50 mL) was treated with the hydrazine hydrate (85%), under 90 C for 5 d. The sovlent was removed leaving oil which was dissolved in ethyl acetate (20 mL) and extracted with water (40 mL). After drying the organic layer with anhydrous Na2SO4 and evaporating the solvent under reduced pressure a solid appeared. The solid was recrystallized from ethanol to obtain the compound 6., 20197-75-5
As the rapid development of chemical substances, we look forward to future research findings about 20197-75-5
