Abstract

Process for the preparation of amino-4 ethane-1,4-dihydro-2,3-quinoline, characterized in that the carboxy-4-ethane-1,4-dihydro-2,3-quinoline is treated or a derivative of this acid by a method that allows transforming a carboxy, carbamoyl, halogenocarbonyl or alkyloxycarbonyl radical into an amino radical, the method being chosen from the group comprising the action of hydrozoic acid on the acid, the action of bromine in an alkaline medium on the amide, the action of an alkaline nitrogen the acid chloride followed by hydrolysis and the action of the hydroxylamine on the ester followed by hydrolysis and the obtained product is transformed into an addition salt with an acid.
