Reaktionsschritte
Reaction of 3β,16α-dihydroxyandrost-5-en-17-one 3β-acetate 1 with a fluorinating agent such as diethyl (2-chloro-1,1,2-trifluoroethyl)amine affords 16α-fluoro-3β-hydroxyandrost-5-en-17-one 3-acetate 3. Hydrolysis of the ester with aqueous acid yields 16α-fluoro-3β-hydroxyandrost-5-en-17-one, 2a. ##STR47##
