실험 절차

3-Fluorophthalic anhydride (4.98 g) and 1-(3-methyl-4-aminobenzyl)-3,5-bis(trifluoromethyl)-1H-pyrazole (9.70 g) were refluxed in acetic acid (43 ml) for 3 hours. After finishing the reaction, the acetic acid was distilled off under the reduced pressure and the obtained crude crystals were washed with t-butyl methyl ether to obtain the aimed 2-{4-[3,5-bis(trifluoromethyl)-1H-pyrazol-1-yl-methyl]-2-methylphenyl}-4-fluoroisoindol-1,3-dione (10.80 g). mp. 158-159° C.
