This invention relates to compounds having the formulae ##STR1## in which: R.sup.1 represents hydrogen, a halogen atom or a lower alkyl radical, a lower alkoxy radical or a lower alkylthio radical; R.sup.2 represents hydrogen or a lower alkyl, aralkyl, aryl, carboxy or alkoxycarbonyl radical; R.sup.3 represents hydrogen, a C.sub.1-12 alkyl radical, or an aralkyl or aryl radical, optionally substituted on the aromatic nucleus with one or more halogen atoms or hydroxy, nitro, cyano, carboxamido, carboxy, alkoxycarbonyl, lower alkyl, lower alkoxy or trifluoromethyl groups; and n is zero or 1. Said new compounds possess therapeutically useful blood-platelet aggregation inhibiting properties and also anti-thrombotic, anti-sludge, antalgic and anti-inflammatory properties.
