    Abstract: The tricyclic intermediate ##STR1## is prepared in a three step sequence from the bicyclic intermediate ##STR2## The key step of this process involves the addition of a Grignard reagent to a mixed anhydride. Tricyclic compound of formula (I) may be readily converted by known methods to valuable steroids.
