Reaction Steps

To a solution of 3-amino-N-{2,6-dibromo-4-[1-(3,5-dichloro-phenyl)-2,2,2-trifluoro-1-hydroxy-ethyl]-phenyl}-benzamide (Example I8) (0.147 mg, 0.24 mmol) in tetrahydrofuran (5 ml) were added successively pyridine (0.058 ml, 0.72 mmol) and 4-cyano-benzoyl chloride (48 mg, 0.29 mmol). The reaction mixture was stirred at ambient temperature for 2 hours. Aqueous sodium hydrogen carbonate (saturated) was added and the phases were separated. The aqueous phase was extracted twice with ethyl acetate. The combined organic extracts were dried over sodium sulfate and concentrated. The residue was purified by column chromatography on silica gel (eluent: cyclohexane/ethyl acetate 1:1) to give the title compound.
