Synthesis
GENERAL METHOD: 2e-k (4 mmol) was dissolved in diphenyl ether with a catalytic amount of 2-chlorobenzoic acid and heated by microwave radiation at 250°C for 1-2 hours. After completion of the reaction, the reaction mixture was cooled, the precipitate 3e-k was collected by filtration and washed sequentially with hexane and water.
