145 °C

To 108 ml of DMSO were added 5.44 g (8.34 mmol) of 2-chloro-N-(2,6-dibromo-4-(perfluorobutan-2-yl)phenyl)-3-nitrobenzamide and 4.90 g (84.3 mmol) of potassium fluoride (spray-dried product), followed by stirring at 145° C. for 2 hours. The reaction solution was poured into ice-water to precipitate the crystal, and the obtained crystals were filtered and washed with hexane. The obtained crystals were purified by silica gel column chromatography (eluent solvent; hexane:ethyl acetate=5:1) to prepare 2.42 g (yield 46%) of a target compound.
