Abstract

A process for preparing 17alpha; -etinyl-19-nortestosterone of formula VIII ** (See formula) ** in 4 conversions, distinguished by that a) the compound of formula I ** (See formula) ** treated with ethylene glycol is transformed into a mixture of isomers of formulas II and III ** (See formula) ** b) the mixture of isomers obtained according to a) is subjected to an oxidation with chromic acid in acetone, methyl isobutyl ketone and pyridine producing the compounds of formulas IV and V c) the mixture of compounds obtained according to b) is treated with a reagent to introduce an ethylenic radical, producing the isomers of the formulas VI and VII. ** (See formula) ** d) finally these compounds are converted by hydrolysis to the desired final product of formula VIII.
