Sulfuric acid magnesium salt (1:1) → N-[2,6-dimethyl-4-{1-hydroxy-2,2,2-trifluoro-1-(trifluoromethyl) ethyl}phenyl]3-(benzoylamino)benzamide

Participants

Reaction Steps

At room temperature, 2.0 g of 2,6-dimethyl-4-[1-hydroxy-2,2,2-trifluoro-1-(trifluoromethyl)ethyl]aniline, 2.7 g of 3-(benzoylamino)benzoyl chloride and 1.2 g of pyridine were introduced to 50 ml of tetrahydrofuran, and the resulting solution was stirred at room temperature. After disappearance of the starting raw material was confirmed by means of TLC, saturated baking soda solution was added to the reaction solution which was stirred for a while. Ethyl acetate and water were added to the reaction solution for solution separation. To a separated organic layer was added anhydrous magnesium sulfate, and the organic layer was dried and filtered off. The filtrate was evaporated to be dried under a reduced pressure and the resulting solid was pulverized to obtain 3.4 g of the desired product (Yield: 95%) in the form of powder.
