Versuchsvorschrift

A 15 mL pressure vessel was charged with 4-tert-butyl-N-[4-iodo-2-(5-ethyl-4-methyl-4H-[1,2,4]triazol-3-yl)-phenyl]-benzenesulfonamide (prepared according to general procedure C, 551 mg, 1.05 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) complex with CH2Cl2 (1:1) (86 mg, 0.105 mmol), triethylamine (290 μL, 2.1 mmol), and DMF/MeOH (4:1) (5 mL). The vessel was placed under an atmosphere of CO (50 p.s.i.), heated to 80° C., and stirred overnight. The following day, the volatiles were removed in vacuo, the residue dissolved in EtOAc, and the organics washed twice with 1 M HCl. The aqueous solution was then extracted three times with EtOAc. The EtOAc extractions were then pooled together and washed with brine. The organic solvent was then removed and the resultant residue was purified by silica gel chromatography to afford 4-(4-tert-butyl-benzenesulfonylamino)-3-(5-ethyl-4-methyl-4H-[1,2,4]triazol-3-yl)-benzoic acid methyl ester as a yellow foam: MS (ES) M+H expected 457.2, found 457.1.
