Procedure
To a solution of 2-chloro-5-[4-chloro-1-methyl-5-(trifluoromethyl)-1H-pyrazol-3-yl]-4-fluorobenzaldehyde (4.5 g, 13.2 mmole) in 40 ml of acetone was added 13 ml (26 mmole) of Jones' reagent. The solution was stirred at ambient temperature for 2 hours and poured into 400 ml of water. The resulting solid was filtered and air dried overnight to afford 4.5 g (96%) of 2-chloro-5-[4-chloro-1-methyl-5-(trifluoromethyl)-1H-pyrazol-3-yl]-4-fluoro-benzoic acid as a white solid. An analytical sample was recrystallized from ether/hexanes; mp 179°-181° C.
