Abstract An increase in the electron-donating capacity of a substitution in position 4 of the pyrimidine ring (OH 〈 SH 〈 NH2) leads to a decrease in the reactivity of a methyl group in position 2. The methyl group in 2-methylpyrimidine is less active than that in 4-methylpyrimidine. The hypothesis has been put forward that the lowering of the reactivity of 2-methylpyrimidine is due to the symmetry of its structure.
