Procedure
To a solution of (R)-3-nitro-4-(pyrrolidin-3-ylamino)benzenesulfonamide (440 mg) in N,N-dimethylformamide (10 mL) was added sodium carbonate (132 mg) and 1-bromo-2-(2-methoxyethoxy)ethane (0.155 mL). The reaction mixture was heated at 60° C. for 18 hours and after an aqueous workup, the crude product was purified on silica gel with a 2.5-10% methanol in methylene chloride gradient to provide the title compound.
