Steps:
General Procedure for the Synthesis of 2-Arylquinoxalines (3a-h)
General procedure: In 25 ml round-bottomed flask, a mixture of 1,2-phenylendiamine (1 mmol), a-bromoacetophenone(1 mmol) and BAILnano-SiO2 catalyst (35 mol%) was preparedand the reaction mixture was stirred at room temperature for the time shown inTable 2. The progress of the reaction was monitored by TLC. After completion of the reaction, ethyl acetate (5 mL) was added and the catalyst was separated by simplefiltration. The residue was dried over anhydrous Na2SO4 and after evaporation ofsolvent the pure product was obtained by recrystallization from ethanol.
