실험 절차

In acetonitrile (100 ml) was dissolved 5.5 g (20 mmol) of 3-iodophthalic anhydride, and a solution (20 ml) of 5.5 g (20 mmol) of 2-methyl-4-[1,2,2,2-tetrafluoro-1-(trifluoromethyl)ethyl]aniline in acetonitrile was slowly dropped thereinto. After the resulting mixture was stirred at room temperature for 3 hours, two-thirds of the acetonitrile was distilled off under reduced pressure and the crystals precipitated were filtered and then washed with acetonitrile to obtain 5.6 g (yield 51%) of 6-iodo-N-{2-methyl-4-[1,2,2,2-tetrafluoro-1-(trifluoromethyl)ethyl]phenyl}phthalamic acid.
