Abstract:

6-(Trifluoromethyl)comanic acid reacts regioselectively with phenylhydrazine in water to give 5-{[}3,3,3-trifluoro-2-(phenylhydrazono)propyl]-1-phenyl-1H-pyrazole-3-c arboxylic acid. Similar reaction in dioxane leads to 3-{[}3,3,3-trifluoro-2-(phenylhydrazono)propyl]-1-phenyl-1H-pyrazole-5-c arboxylic acid. A strong solvent influence on the reaction route was also found for 6-(trifluoromethyl)comanic acid derivatives. (C) 2009 Elsevier Ltd. All rights reserved.
