A convenient and general method for the preparation of sixteen 3,5-diarylsubstituted
2,4- and 2,6-dimethylpyridines of high forensic importance is described. The Suzuki
cross-coupling reaction between a range of ring-substituted phenylboronic acids and
3,5-dibromo-2,4-dimethylpyridine and 3,5-dibromo-2,6-dimethylpyridine was used as
a key step.
