摘要：
The first examples of a direct introduction of an aryl group onto a pyrazole ring via palladium-catalyzed cross-coupling reactions are reported. It was found that substituents at 1-position on the pyrazole ring affected the yields, and dimethylsulfamoyl group, as an electron-withdrawing group, gave highest yield.
