Reaction Conditions

Reaction Steps

To a solution of 4-trifluoromethyl aniline (213 μL, 1.70 mmol) in pyridine (270 μL) was added 2-(trichloroacetyl)-2,3-dihydro-1 H-isoindole-5-sulfonyl chloride (617 mg, 1.70 mmol) at room temperature, and the mixture was stirred at 60° C. for 1.5 hr. The reaction mixture was allowed to cool to room temperature and diluted with ethyl acetate. The mixture was washed with 1 mol/L hydrochloric acid, brine and water. The organic layer was dried over anhydrous sodium sulfate and then the desiccant was filtered off, followed by concentration under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1→2:1) to afford the title compound as a colorless powder (586 mg).
