Аннотация
In this work, amide, isoquinoline were synthesized and the kinetics of the reaction of homoveratrylamine with brassilic acid was studied by HPLC. The conditions of (high-performance liquid) chromatographic separation were revealed, which allow satisfactory separation of the components of the reaction mixture consisting of reagents, intermediates and products of the reactions of condensation and cyclization. By studying the kinetic laws, it was found that the reactions of condensation and cyclization obey the first-order kinetic equation and the activation energy is, respectively, 172.3 kJ / mol for the amide condensation reaction, and 118.8 kJ / mol for the cyclization reaction.
