Steps:

4.2. General Procedure for the Synthesis of 1b-7b and 11b.
General procedure: A 100mL round-bottom flask was equipped with a magnetic stir bar and a reflux condenser. To xylene (10.0mL), tetradecyltrimethylammonium bromide (1.1mmol) and a heterocyclic compound (1.0mmol) were added, followed bya solution of NaOH 50% (5.0 mL). The mixture was stirred at reflux temperature for 2-18 h. After completion of thereaction, the mixture was air-jet cooled to 25 °C and TLC indicated the disappearance of the starting material. The reaction mix was treated with AcOEt (4 × 20 mL), and the organic phase separated and removed under reduced pressure. The residue was purified to analytical purity by column chromatography.
