Abstract
Procedure for obtaining hydrazides of thiazolecarboxylic acids of the general formula ** (see formula) ** in which for each particular case only one of the three symbols RR1 or R2 has the meaning of substituted or unsubstituted carbohydrazine as indicated below while all these three symbols when they do not have the said meaning can represent hydrogen or interior alkyl or aryl or aralkyl radicals. The carbohydrazine group may or may not be substituted according to one of the following general formulas ** (see formula) ** in which R can be hydrogen or a lower alkyl R4 and R 5 can be the same or different and represent in formula I hydrogen alkyl haloalkyl aryl or aralkyl and in formula II, in addition to the above, also carboxyl or carbakoxy or carbalkoxyalkyl radicals free or combined in salts which procedure consists in react a compound of the formula ** (see formula) ** with a compound of the formula ** (see formula) ** in which RR1 and R2 in addition to the meanings Finishes to mention can also have those of carboxy or carbalkoxy in anhydrous and hot conditions with or without solvent.
