The addition of methanesulfonic acid to N -(2,6-dimethylpyridin-4-yl)- N -methyl-2- iso -propylaniline led to the selective protonation of the pyridine nitrogen atom, resulting in a significant deceleration of the rotation rates around both N -pyridyl and N -( i -Pr)phenyl bonds through a relayed brake mechanism.
