The reaction mixture was heated to 70° C. After 6 hours, the reaction mixture was diluted with ethyl acetate, washed with 1N aqueous sodium hydroxide and brine, then dried over magnesium sulfate, filtered, and concentrated. The residue was purified by column chromatography on silica gel (ethyl acetate/hexanes gradient) to afford 5-cyclopropyl-4-iodo-1-phenyl-1H-pyrazole.
