Abstract:
Compounds of the formula: ##STR1## wherein: A is oxo or dioxo;R.sup.1, R.sup.2 and R.sup.3 are independently hydrogen or lower alkyl of one to six carbon atoms;R.sup.4, R.sup.5, R.sup.6 and R.sup.7 are independently hydrogen, lower alkyl of one to six carbon atoms, alkoxy, acyl or halo;are advantageously converted to thieno[3,2-c]pyridine derivatives and the pharmaceutically acceptable salts thereof, particularly ticlopidine hydrochloride.
