"Ye Hong et al. used benzylamine and methyl acrylate as starting materials, employing microwave radiation for Michael addition and Dieckmann condensation. They tested different microwave radiation times, powers, and temperatures. The optimal Michael addition conditions were set at a microwave power of 110-120 W, with a microwave reaction temperature of 50-55°C and a radiation time of 80 minutes. The best Dieckmann condensation conditions were set at a microwave power of 90-100 W, with a microwave reaction temperature of 70-75°C and a radiation time of 20 minutes. The final product, N-Benzyl-4-piperidone, was synthesized through decarboxylation by heating and hydrolysis."
