Synthesis of 1-Aryl-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic Acids and Esters

Ethyl 1-aryl-5-(trifluoromethyl)-1H-pyrazole-4-carboxylates 2 were prepared by the condensation of arylhydrazines with ethyl 3-ethoxy-2-(trifluoroacetyl)-2-propenoate (1a) at low temperature.The corresponding acids were also synthesized.X-ray diffraction analysis of an amide derivative 4 verified the position of the trifluoromethyl group on the pyrazole ring.
