Reaction Steps

1-(5-Chloro-4-fluoro-2-hydroxy-3-iodophenyl)ethanone (13 g, 41 mmol) was dissolved in N,N-dimethylformamide (41.3 mL). Methyl iodide (3.9 mL, 62 mmol) was added followed by potassium carbonate (11 g, 83 mmol). The reaction was heated at 60° C. for 1 hour. The mixture was cooled to room temperature, diluted with ether. The organic layers were separated and combined, washed with water, dried over MgSO4, concentrated and purified on silica gel (eluting with 0 to 10% EtOAc in hexanes) to give the desired product (10 g, 70%). LCMS calculated for C9H8ClFIO2 (M+H)+: m/z=328.9; Found: 328.9.
