Reaction Steps
4-chloro-3-nitrobenzenesulfonamide (1.300 g), 1-(2,2,2-trifluoroethyl)piperidin-4-amine hydrochloride (1.201 g), and triethylamine (2.30 mL) were added to 1,4-dioxane (50 mL) and water (5 mL) and heated at 90° C. for 16 hours. The solution was concentrated on vacuum and purified by flash column chromatography on silica gel with ethyl acetate increasing to 5% methanol in ethyl acetate.
