実験手順

To a stirred solution of 3-methylsulfanyl-propionic acid (120 mg, 1.0 mmol) under an inert atmosphere in 6 mL of anhydrous DCM and DMF (200 μL) was added oxalyl chloride (89 μL, 1.0 mmol). The resultant solution was stirred at room temperature overnight and then added to a solution of 4-tert-butyl-N-(4-chloro-5-fluoro-2-hydrazinocarbonyl-phenyl)-benzenesulfonamide (400 mg, 1.0 mmol) and Et3N (0.35 mL, 2.5 mmol) at 0° C. The resultant solution was stirred at room temperature for 4 hours and the solvent was removed in vacuo. The residue was purified via automated silica gel chromatography to afford 4-tert-butyl-N-{4-chloro-5-fluoro-2-[N′-(3-methylsulfanyl-propionyl)-hydrazinocarbonyl]-phenyl}-benzenesulfonamide as an oil: MS (ES) M+H expected 502.1, found 502.0.
