Reaction Steps

1-(4-Chlorophenyl)-5-methylpyrazole-4-carboxylic chloride (1.7 g) was added to a pyridine solution of 4-chloro-3-nitroaniline (1 g) and the mixture was stirred at room temperature for 2 h. After the reaction, water was added and the precipitated solid was collected by filtration to give the title compound (2.1 g), melting point:221–225° C.
