Reaction Steps

K2CO3 (210 mg, 1.52 mmol) and I2 (390 mg, 1.52 mmol,) were added to a solution 2-anilino-7-chloro-5-methyl-1-phenyl-1,8-naphthyridin-4(1H)-one (500 mg, 1.38 mmol) in DMF (10 mL). The mixture was stirred for 30 min and then poured into an aqueous solution of saturated Na2S2O3 (10 mL). The aqueous solution was extracted with EtOAc. The combined organic extracts were dried over MgSO4, and concentrated in vacuo. Silica gel flash chromatography of the residue using 4:1 to 1:1 Hex:EtOAc afforded 2-anilino-7-chloro-3-iodo-5-methyl-1-phenyl-1,8-naphthyridin-4(1H)-one (380 mg, 56%): LCMS RT: 3.45 min, MH+: 488.2, Rf=0.5 (2:1 Hex:EtOAc).
