الإجراء التجريبي

To a solution of 3-[(4-chloro-2-{[(4-chloro-2-fluorophenyl)sulfonyl]amino}phenyl)sulfanyl]propanoic acid (297 mg, 0.70 mmol) in DMF (2 ml) was added EDC.HCl (148 mg, 0.77 mmol), HOBT.H2O (104 mg, 0.77 mmol), and N-methylethanamine (0.30 ml, 3.5 mmol). The reaction was stirred at room temperature for 16 hours, diluted with 1M HCl, extracted with EtOAc. The organic layer was washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (10-40% EtOAc in hexane) to yield the title compound (269 mg, 83%) as a mixture of amide bond cis-trans isomers.
