The title compounds, a mixture of anti and syn diastereomers, were prepared by Pd- catalyzed coupling of areneboronic acids with hetaryl halides. Energy barriers for the interconversion of the diastereomers obtained by kinetic and computational studies show a dependence on the location of the annular nitrogen atom, the ortho providing a smaller barrier than the meta nitrogen atom.
