Abstract

The regioselectivity of the addition of 2, 4, 6-trimethylphenol to 2, 4-dichloro-3, 6- dimethylpyridine can be controlled by the proper choice of catalyst and solvent. The use of catalytic copper (I) salts and pyridine as solvent results in exclusive addition at C-2. In their absence, a mixture of regioisomers is obtained in which addition at C-4 is dominant.
