    • Typical experimental procedure under microwave irradiation: Cyclic secondary amine (2.5 equiv) was treated with 4-fluorobenzaldehyde (1.24 mL, 11.6 mmol) and active methylidene (11.6 mmol) in EtOH (20 mL). The resulting mixture was placed into the microwave reactor for a specified reaction time. After the reaction was completed, the mixture was cooled down to rt and poured into 50 mL of water. Crude products were filtered off and purified by crystallization in EtOH.

    • 3). Then 5a (2.54 g, 11.6 mmol) was dissolved in EtOH (20 mL). The resulting solution was treated with cyclic secondary amine (2.5 equiv) and heated to reflux for 3 h. Then the mixture was cooled down to room temperature and poured into 50 mL of water. Crude products were filtered off and purified by crystallization in EtOH.
