The present invention relates to new amino-thiazole and amino-oxazole derivatives of the general formula:
wherein:
R represents hydrogen, a lower alkyl group with 1 to 4 carbon atoms, a lower alkenyl group, a phenyl-alkyl (1-4 C), furanyl-alkyl (1-4 C) or thienyl-alkyl (1-4 C) group;
X represents sulphur or oxygen;
R₁ and R₂ represent hydrogen or alkyl (1-4 C), and
the dotted line represents an optional extra bond, as well as pharmaceutically acceptable acid addition salts thereof, having potent dopamine-agonist activity.
