الإجراء التجريبي

To a stirred solution of 4-[4,5-dihydro-5-(3,4,5-trichlorophenyl)-5-(trifluoromethyl)-3-isoxazolyl]-N-[2-[S-methyl-N-(2,2,2-trifluoroacetyl)sulfinimidoyl]ethyl]-1-naphthalene-carboxamide (70 mg) (i.e. the title compound of Step A) in methanol (2 mL) was added potassium carbonate (300 mg) at room temperature. After stirring overnight at room temperature, the reaction mixture was filtered through a short pad of silica gel and rinsed with ethyl acetate. After concentration, the residue was purified by column chromatography on silica gel using dichloromethane/methanol (98:2 to 92:8) as eluent to afford the title compound, a compound of the present invention, as a semisolid (9 mg, 15% yield).
