Reaction Steps

To a solution of 4-fluoro-3-nitrobenzenesulfonamide (1.4 g) in tetrahydrofuran (30 mL) was added 1,4-dioxaspiro[4.5]decan-8-amine (1.0 g) and diisopropylethylamine (5 mL). The mixture was stirred overnight. The mixture was diluted with ethyl acetate (300 mL) and washed with water, brine and dried over Na2SO4. Filtration and evaporation of the solvent gave the title compound.
