To a solution of 5-bromonicotinic acid (648 mg, 3.21 mmol), methyl [3-(S-methylsulfonimidoyl)phenyl]acetate (802 mg, 3.53 mmol), and catalytic DMAP in 15.0 ml DMF at room temperature was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (738 mg, 3.85 mmol). The reaction was stirred 1 hour at room temperature then added to EtOAc. The EtOAc solution was washed with dilute brine, NaHCO3 solution, brine, dilute HCl/brine mixture, brine/NaHCO3 solution, dried with anhydrous Na2SO4 and rotary evaporated. The oil was chromatographed eluting with CHCl3/EtOAc to give viscous clear oil (994 mg, 75%).
