実験手順
The product of step b is added to the t-butanol. The mixture is heated and stirred then the H2O is added and the KMnO4 is added in portions over about 30 minutes at 75° C. The mixture is refluxed for 90 minutes. The product is worked up to give crystals of the desired 4-phenyl-2,6-pyridinedicarboxylic acid. The dicarboxylic acid which results is useful in its own right in the present invention as a ligand.
