Tetrahydrofuran → HCID 86610222, compound

Participants

Reaction Steps

First, to an anhydrous tetrahydrofuran solution (15 ml) of 0.5 g of N-(2,4-bistrifluoromethylphenyl)3-isocyanatobenzamide produced in Example 10-1 were added 0.40 g of 2,2,3,3,3-pentafluoro-n-propanol and 0.13 g of triethylamine, and the resultant mixture was stirred at room temperature for 5 hours. The mixture was diluted with ethyl acetate (20 ml), and an organic layer was washed with a 1N sodium hydroxide aqueous solution and 1N hydrochloric acid. The solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (eluent; hexane:ethyl acetate=4:1) to obtain 0.49 g (yield 70%) of the title compound.
