실험 절차

To a stirred suspension of 4-[5-(3,5-dichlorophenyl)-4,5-dihydro-5-(trifluoromethyl)-3-isoxazolyl]-N-[2-(methylsulfinyl)ethyl]-1-naphthalenecarboxamide (i.e. the title product of Step B) (180 mg), 2,2,2-trifluoroacetamide (75 mg), MgO (53 mg), and Rh2(OAc)4 (4 mg) in dichloromethane (4 mL) was added PhI(OAc)2 (160 mg) at room temperature. The resulting mixture was stirred for 5 h 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 acetate (3:7 to 1:9) as eluent to afford the title compound, a compound of the present invention, as yellow oil (100 mg, 46% yield).
