Participants

Reaction Steps

To a solution of EXAMPLE 350C (89 mg) in N,N-dimethylformamide (3 mL) was added NaH (65% in mineral oil, 36 mg). The mixture was stirred for 30 minutes, and then 5,6-dichloropyridine-3-sulfonamide (85 mg) was added. The mixture was stirred overnight. The mixture was poured over aqueous NH4Cl and extracted with ethyl acetate (100 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 eluted with 30% ethyl acetate in hexane to provide the title compound.
