Abstract
The synthesis of 2-(2-methylaminoethyl)pyridine from the reaction between 2-vinylpyridine and methylamine serves as a crucial exploration into the reversibility of the aza-Michael reaction. The results unequivocally demonstrate the notable reversibility inherent in the aza-Michael reaction. This characteristic assumes a pivotal role in fostering heightened selectivity, particularly in the realm of Flow Chemistry, where operating temperatures surpass the typical boiling points of the involved mixtures. A preliminary kinetic model, grounded in first-order reactions, aligns well with the experimental data. Results from microwave and Flow Chemistry allow for an initial approximation of the parameters governing the observed equilibrium, providing a foundational understanding of the reaction dynamics. This insight into the reversibility and kinetic aspects of the aza-Michael reaction contributes to the optimization of conditions for enhanced control and efficiency in synthetic processes, particularly under the unique conditions presented by Flow Chemistry.
