Abstract
Process for obtaining thioamine esters, characterized in that starting from the compounds of formulas II a, II b, II c, III, IV, V, VI, VII a, VII b, VIII a, VIII b, VIII c, and IX, until thioamine esters of the general formula are obtained: ** (See formula) ** in which, at least one of the radicals R-1 and R-2, occupies a thiocarboxylic group esterified by an aromatic, aliphatic, arylaliphatic alcohol, optionally substituted and the other of the radicals R-1 and R-2 occupies it optionally a hydrogen atom, R-3 and R-4 are the same or different and represent hydrogen, alkyl radicals, acyl groups or arylalkyl radicals, hetero-alkyl heterocyclic, arylalkyl or phenyl, optionally substituted or constitute together with the nitrogen atom a heterocyclic radical, in which R-5 and R-6 are the same or different and represent hydrogen, low alkyl radicals or phenyl radicals, optionally substituted and where m and m are the same or different and represent the numbers 0, 1, 2, or 3 and as long as the compounds contain alkali groups, the production of their salts is also claimed.
