Abstract:Betamethasone 21-acetate was prepared using 9β,11β-epoxy-16β- methylpregna-1,4-diene-17α,21-diol-3,20-dione (DB11) as the starting material through fluorination and esterification with a total yield of 66% and a purity of 99.93%(HPLC). The product structure was also confirmed by MS and NMR. The raw materials in this process were cheap and easy to obtain while the cost were low. This process was suitable for the industrial production.
Key words:Betamethasone; Betamethasone 21-acetate; synthesis
