実験手順
A mixture of 4-iodo-1-methyl-1H-pyrazole-5-carboxylic acid ((Manaev, Yu. A. et al., J. Gen. Chem. USSR (Engl. Transl.), 1982, 52 (11), 2291), 500 mg, 1.98 mmol), 4-fluoroaniline (0.94 ml, 9.90 mmol), copper powder (200 mg) and 5% aqueous sodium carbonate (10 ml) was stirred for 16 h at 100° C. After cooling to room temperature, 2N aqueous sodium hydroxide (100 ml) and diethyl ether (50 ml) were added to the mixture. The mixture was filtered through a pad of Celite. The water layer was separated, washed with diethyl ether (50 ml) and acidified with concentrated hydrochloric acid. The formed precipitate was collected by filtration and dried to give 282 mg (61%) of the title compound as a white solid.
