Versuchsvorschrift

tert-Butyl ((1-((3-(2-(dimethylamino)-2-oxoethoxy)phenyl)sulfonyl)-5-(2-fluorophenyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 9c (54 mg, 0.10 mmol) was dissolved in 4 mL of dichloromethane, and the reaction solution was cooled in an ice bath, followed by dropwise addition of a solution of hydrogen chloride in 1,4-dioxane (4 N, 4 mL). After removing the ice bath, the reaction solution was stirred at room temperature for 3h. A saturated sodium bicarbonate solution was added dropwise until the pH of the reaction solution was 7 to 8, 5 mL of water were added, and then the reaction solution was extracted with ethyl acetate (10 mL×3). The organic phases were combined, dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure to obtain the title product 2-(3-((2-(2-fluorophenyl)-4-((methylamino)methyl)-1H-pyrrol-1-yl)sulfonyl)phenoxy)-N,N-dimethylacetamide 9 (20 mg, a yellow solid) in 45% yield.
