Abstract

Procedure for the preparation of heterocyclic compounds, characterized in that a compound of the general formula ** formula ** is condensed where R1 represents an alkyl radical with 11 to 18 carbon atoms, R2 represents a saturated or unsaturated lower alkyl or cycloalkyl radical, which may be substituted by one or more halogen atoms, R3 represents a cyano or carbalkoxy group and R4 represents a lower alkyl group, with thiourea and, in the event that a compound of formula II in which R3 represents a cyano group is subjected to condensation, the obtained 4-imino-thiobarbituric acid is hydrolyzed, (Machine-translation by Google Translate, not legally binding)
