    摘要： There are described intermediates for the preparation of known pyrazoloazole photographic magenta dye forming couplers and processes for making and using these intermediates. The intermediates are low molecular weight compounds represented by the structure: ##STR1## wherein: R, X, R.sup.1 and Y are defined herein. The process for making these intermediates involves diazotizing a 5-amino-1H-pyrazole to produce a 5-diazo-1H-pyrazole, then condensing the diazotized product with an active methine or methylene compound having a pKa of 14 or less to produce a substituted hydrazone and then subjecting the hydrazone to cyclization and reduction, in either order.

    摘要： The invention provides a process for preparing a 4-amino-5-mercapto-3-substituted-�1,2,4!triazole comprising reacting a thiocarbohydrazide with a carboxylic acid in the presence of an organic solvent and a boron compound having the formula ##STR1## where R.sup.2, R.sup.3, and R.sup.4 are independently selected from the group consisting of hydrogen, hydroxy, amino, alkyl, aryl, alkoxy, and aryloxy groups. The process provides a safer low temperature process for preparing the desired compound.
