3-?Nitro-?4-?(((tetrahydro-?2H-?pyran-?4-?yl)?methyl)?amino)?benzenesulfonamide is a reagent used in the synthesis of BTK, PI3K and JAK-2 inhibitors.

3-nitro-4-((tetrahydro-2H-pyran-4-yl)MethylaMino)benzenesulfonaMide(1228779-96-1) is prepared by the reaction of 4-Aminomethyltetrahydropyran and 4-Fluoro-3-nitrobenzenesulfonamide. The specific synthesis steps are as follows:
4-Fluoro-3-nitrobenzenesulfonamide (1.0 g, 4.54 mmol), (tetrahydro-2H-pyran-4-yl)methylamine (0.6 g, 4.49 mmol), Triethylamine (1.3 g, 6.81 mmol) was added to 10 ml of tetrahydrofuran solution. After stirring at room temperature for 5 h, the solvent was removed. Add 20ml of methanol to beat, After drying, the product was obtained in an amount of 1.4 g. The yield was 97percent.
