Procedure: A solution of 4-fluoro-2-methoxy-phenol (3.0 g, 21.1 mmol) in acetone (250 mL) is treated with cesium carbonate (8.3 g, 25.3 mmol) followed by 2-bromo-1-(4-bromo-phenyl)-ethanone (5.9 g, 21.1 mmol). The resulting mixture is stirred at room temperature for 2 h. Water (600 mL) is added slowly to the vigorously stiffing solution. After stirring for 30 minutes, the precipitate is filtered off and washed with copious water to give 1-(4-bromo-phenyl)-2-(4-fluoro-2-methoxy-phenoxy)-ethanone (G-1).

After 15 minutes of stirring the phases were separated and the aqueous phase was washed with toluene (7.5 L). With stirring, EtOAc (15.0 L) was added to the aqueous phase, followed by 6 M HCl (5.6 L) keeping the internal temperature below 30° C. The layers were separated and the organics were dried over magnesium sulfate. Filtration through a pad of celite and concentration provided a solid that was reslurried in 915 mL of EtAOc and 9.2 L of heptanes. Stirring was continued for 1 hour before the solids were filtered and washed with heptanes.
