실험 절차

To a stirred suspension of 4-[4,5-dihydro-5-(3,4,5-trichlorophenyl)-5-(trifluoromethyl)-3-isoxazolyl]-N-[2-(methylthio)ethyl]-1-naphthalenecarboxamide (prepared analogously as described for the compound of Example 3, Step A) (200 mg), 2,2,2-trifluoroacetamide (80 mg), MgO (57 mg), and Rh2(OAc)4 (4 mg) in dichloromethane (4 mL) was added PhI(OAc)2 (172 mg) at room temperature. The resulting mixture was stirred overnight at room temperature, then filtered through a short pad of Celite® diatomaceous filter aid, and rinsed with ethyl acetate. The filtrate was concentrated, and the residue was purified by column chromatography on silica gel using hexanes/ethyl acetates (1:1 to 1:4) as eluent to afford the title compound as a semisolid (70 mg, 30% yield).
