Reaction Conditions

Reaction Steps

A sample of 3-bromoaniline (2.00 g, 11.6 mmol), 4-butylphenylboronic acid (3.1 g, 17.4 mmol) and cesium fluoride (5.3 g, 35 mmol) are charged to a microwave reaction vial and treated with anhydrous dioxane (12 mL) and bis(tri-tert-butylphospine) (600 mg, 1.16 mmol). The vial is sealed and purged with nitrogen for 5 minutes. The reaction is then heated to 120° C. for 5 minutes and filtered over celite washing with ethyl acetate. The solvent was removed and the crude material was purified by UV triggered reverse phase HPLC to afford the title compound: ESMS m/z 226.2 (M+H+).
