Mode opératoire

To a mixture of potassium carbonate (4.30 g, 53.3 mmol) in N,N-dimethylformamide (47 mL) and methanol (5 mL) at 50° C. was added a solution of 2-(bromomethyl)-1-chloro-4-iodobenzene (i.e. the product of Step A) (5.20 g, 15.7 mmol) in N,N-dimethylformamide (10 mL). The reaction mixture was heated at 110° C. for 1 h and then cooled to room temperature. The reaction mixture was partitioned between diethyl ether (200 mL) and water (200 mL), the organic layer was separated, washed with water (3×50 mL), dried over magnesium sulfate, filtered and concentrated under reduced pressure to provide the title compound as a yellow oil (4.32 g).
