Novel process steps and novel processes for producing unsubstituted and substituted meta- and para- cyano benzoic acid compounds, as well as salts and derivatives thereof, and intermediates therefor which are useful as intermediates for producing platelet aggregation inhibitors. Further disclosed are processes for producing bicyclic and heterocyclic cyano substituted compounds also having a carboxyl group attached to the same ring structure.
