摘要:
A process for producing a compound of formula (I): ##STR1## wherein the dotted lines - - - independently represent a single or double bond and R, R.sub.1, R.sub.2 and R.sub.3 are each hydrogen or an organic radical, comprises treating the corresponding 17.beta.-carbonylimidazole intermediates with anhydrous acids in the presence of an amine and, optionally, hydrogenating the resulting compound.
