Alkoxytriazolinones of the formula (I) ?known for example as intermediates for preparing agrochemically active compounds! STR1 wherein R represents an alkyl group, an alkenyl group, an alkinyl group, a cycloalkyl group, a cycloalkylalkyl group, an aryl group or an arylalkyl group, any of which may be substituted, are prepared by reacting a) thioimidodicarboxylic diesters of the general formula (II) STR2 wherein R is as defined above and R1 represents an alkyl group, an arylalkyl group or an aryl group, any of which may be substituted, with b) hydrazine, hydrazine hydrate or an acid adduct of hydrazine. The reaction is conducted i) in the presence of a diluent and, optionally, in the presence of a basic reaction auxiliary, and ii) at temperatures between -10° C. and +100° C.
