Reaction Steps

Ethyl pyrazole-4-carboxylate is reacted with 1-(bromomethyl)-3-(trifluoromethyl)benzene in acetone in the presence of potassium carbonate. The product, ethyl 1-{[3-(trifluoromethyl)phenyl]methyl}pyrazole-4-carboxylate, is then hydrolyzed with potassium hydroxide in methanol, to provide 1-{[3-(trifluoromethyl)phenyl]methyl}pyrazole-4-carboxylic acid.
