Reaction Steps

To 4-fluoro-3-nitrobenzenesulfonamide (0.272 g) and (R)-1-(1,3-difluoropropan-2-yl)pyrrolidin-3-amine (0.195 g) in tetrahydrofuran (3.0 mL) was added N-ethyl-N-isopropylpropan-2-amine (0.512 mL) and the reaction was stirred at room temperature. After stirring for 6 hours, the reaction was concentrated, loaded onto silica gel (Reveleris 40 g) and the product was purified by flash chromatography using a gradient of 25% to 100% ethyl acetate:hexanes over 30 minutes to provide the title compound.
