摘要：

The 1H-pyrazole-3-carboxylic acids 2 or their remarkably stable acid chlorides 3 can easily be converted into the corresponding 1H-pyrazole-3-carbonyl-N'-urea derivatives (5a-k) from reaction with urea nucleophiles. It has been demonstrated that with the variation in reaction conditions, the reaction changes thus leading to different products. All newly synthesized compounds were characterized by elemental analysis, FT-IR, H-1 and C-13 NMR spectral data. All compounds were compared with their previous analogues.
