Reaction Steps

1-(5-Chloro-2-hydroxy-3-iodo-4-methylphenyl)ethanone (18.9 g, 60.9 mmol) (from Example 1, Step 1) was dissolved in N,N-dimethylformamide (60.8 mL). Iodoethane (7.3 mL, 91 mmol) was added followed by potassium carbonate (17 g, 120 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 combined, washed with water, dried over MgSO4, concentrated and purified on silica gel (eluting with 0-10% EtOAc in hexanes) to give the desired product (18.9 g, 91.7%). LCMS calculated for C11H13ClIO2 (M+H)+: m/z=339.0; Found: 339.0.
