The first reported synthesis of the pyrazole acid was in 1993, by chemists at Monsanto. [7]The ethyl ester of difluoroacetoacetic acid is treated with triethyl orthoformate in the presence of acetic anhydride [8] and then with methyl hydrazine, which forms mainly the required pyrazole ring, in addition to its isomer with the methyl group on the alternative nitrogen atom.
