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.
