実験手順
A mixture of 2-[5-Chloro-3-(4-chloro-3-trifluoromethyl-benzenesulfonylamino)-pyridine-2-carbonyl]-benzoic acid (18 mg, 0.0347 mmol) and 2.3 mg of hydrazine hydrate in 1.0 ml of ethanol was refluxed for 4 hours. After cooled to room temperature the mixture was concentrated and the residue was purified via preparative TLC to afford 12 mg of title compound as a white powder. MS: (M+H)/z=515.2.
