Reaction Steps

To a solution of 3-amino-2-[4-(methylsulfonyl)phenyl]pyridine (1.0 eq.) in AcOH:CH2Cl2 (1:1, 0.13 M) at −20° C. was added I2 (1.5 eq), KI (1.5 eq) then NaNO2(1.5 eq). The mixture was stirred at 20° C. for 2 h then diluted with EtOAc and water. The organic extracts were washed with aqueous NaHCO3, brine, dried over MgSO4, filtered and concentrated. Flash chromatography (Hex:EtOAc; 40:60) afforded the title compound as a white solid.
