Pyridine and 2,6-lutidine were methylated with methyl chloride in bromobenzene solution in sealed glass ampoules at 100.0/sup 0/C. The ionic chloride was isolated, purified, and completely reconverted to methyl chloride. Isotope ratios were determined with an isotope ratio mass spectrometer. It appears that the increase in the transition state is a manifestation of the Hammond postulate--the most hindered and slowest reaction possessing the most product-like transition state. 1 table.
