A mixture of 5-fluoro-2-nitrotoluene (2.33 g), 4-iodo-1H-pyrazole (2.91 g) and potassium carbonate (2.49 g) was heated and stirred in DMF (30 ml) at 140° C. for 4 hours. After cooling to room temperature, the reaction mixture was poured into ice water to separate out crystals. The obtained crystals were filtered, washed with water and dried, and 4-iodo-1-(3-methyl-4-nitrophenyl)-1H-pyrazole (4.60 g) was obtained.
