実験手順
A 3.5 gram portion of the atropic ester of Example 1 was reacted with 2.7 grams α,α,α-trifluoro-3-tolylhydrazine hydrochloride in the presence of triethylamine to produce 2.4 grams 1,4-bis-(α,α,α-trifluoro-3-tolyl)-3-pyrazolin-5-one, m.p. 207°-208° C. A 1.8 gram portion of the above pyrazolinone was alkylated with 2 grams methyl iodide to produce 1.25 grams of the desired product, m.p. 110°-111° C.
