Reaction Steps

1-(2-Methoxy-ethyl)-piperidin-4-ylamine (2.01 g) and triethylamine (3.24 mL, 2.35 g) were added to 1,4-dioxane (60 mL). 4-Chloro-3-nitrobenzenesulfonamide (2.50 g) was added, and the mixture was heated to 90° C. for 16 hours. The mixture was cooled and the material purified by flash column chromatography on silica gel using 10% methanol in dichloromethane.
