Potassium Carbonate → HCID 11654119, compound

Participants

Reaction Steps

A degassed solution of 3-(4-iodo-phenoxymethyl)-benzoic acid methyl ester (of Inter-mediate 1; 74 mg, 0.2 mmol) in dioxane (4 mL) and a degassed solution of potassium carbonate (83 mg) in water (0.4 mL) were added to a reaction vial containing (2-phenoxy)phenylboronic acid (available from Aldrich Chemical Company, Inc., Milwaukee, Wis.; 128 mg, 0.6 mmol). The solution was degassed and bis(tri-cyclohexylphos-phine)palladium (available from Strem Chemicals, Inc., Newburyport, Mass.; 7 mg, 0.01 mmol) was added. The mixture was heated in a microwave oven at 170 degrees for 25 min. The reaction mixture was filtered through silica, and washed with dioxane (1 mL) and dimethylacetamide (1 mL). 2 M potassium hydroxide solution (0.4 mL) was added. The mixture was stirred at room temperature overnight, and then 1 M HCl (0.8 mL) was added. The solvent was evaporated and the residue was triurated with 50% aqueous methanol to give 3-(2′-phenoxy-biphenyl-4-yloxymethyl)-benzoic acid. Mass spectrum MH+=397.
