実験手順

To a solution of EXAMPLE 350C (495 mg) in N,N-dimethylformamide (6 mL) was added NaH (65% in mineral oil, 320 mg). The mixture was stirred for 30 minutes, and then 4-fluoro-3-nitrobenzenesulfonamide (457 mg) was added. The mixture was stirred overnight. The mixture was poured over aqueous NH4Cl and extracted with ethyl acetate (300 mL). The combined organic layers were washed with water, brine and dried over Na2SO4. After filtration and evaporation of the solvent, the residue was loaded on a silica gel cartridge and was eluted with 30% ethyl acetate in hexane to provide the title compound.
