Abstract
Procedure for preparing 3- (1,3,4-tindiazol-2-yl) -5-hydroxyhydantoins, of formula ** (See formula) ** wherein R is alkyl, halogenoalkyl, alkylmercapto, or alkylsulfonyl and R1 is alkyl; characterized by that parabolic acid derivatives of the formula ** (See formula) ** in which R and R1 have the meanings defined above, they are reacted with hydrogen, in the presence of catalysts and optionally aqueous acids or bases, or with hydrogen donating substances, such as sodium borohydride or lithium aluminum hydride, in presence of polar solvents, at temperatures from -20 to + 20ºC, preferably between -10 and + 5ºC, approximately.
