Pyridine → 2,6-Dimethyl-4-(nonafluoro-2-butyl)phenyl 3-[(2,2,2-trichloroethoxy)carbonylamino]benzamide

Participants

Reaction Steps

First, to a solution prepared by adding 0.34 g of 2,6-dimethyl-4-(nonafluoro-2-butyl)aniline and 0.09 g of pyridine to 5 ml of tetrahydrofuran and stirring the resultant mixture at room temperature was added 0.33 g of 3-[(2,2,2-trichloroethoxy)carbonylamino]benzoyl chloride produced in Example 9-2. After reaction for 5 hours, ethyl acetate and water were added to the reaction solution, and a separating operation was performed. Then, an organic layer was separated and dried with anhydrous magnesium sulfate. The solution was filtered, and then the filtrate was collected, and the solvent of the filtrate was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (eluent; hexane:ethyl acetate=4:1) to obtain 0.45 g (yield 71%) of the title compound as a solid.
