Reaktionsschritte

A solution of 4-hydroxy-3-methylbenzaldehyde (1.0 equiv) in DMF (0.2 M solution) was treated with K2CO3 (1.5 equiv) and 6-chloronicotinamide (1.0 equiv). The reaction mixture was placed inside the microwave oven and then irradiated for 5 min. Upon completion of the reaction, the mixture was cooled, poured into H2O and extracted with ethyl acetate, and the combined organic layers were washed twice with water and brine. After drying the extracts over magnesium sulfate and evaporation under vacuum the crude product was purified by silica gel chromatography using CHCl3: EtOH 7%: NH4OH 0.7% to afford the title compound as a solid.
