  • Patent number: 4692529
    Abstract: A method for synthesizing a magenta coupler. The synthesis is carried out through (1) 3-pyrazoline-5-ones which are obtained by substituting a blocking group at the nitrogen atom in the second position thereof; or (2) pyrazoles which are obtained by substituting a blocking group at the hydroxyl group bonded in the fifth position thereof. The magenta coupler obtained has the formula ##STR1## wherein R.sub.1 is an aryl or heterocyclic group, R.sub.2 is an acylamide, anilino or ureido group, and R3 is an alkyl, aryl, or heterocyclic group.
