Scheme VI, Step A′: Into a 10 mL single neck flask was placed [2-fluoro-2-(4-iodophenyl)propyl][(methylethyl)sulfonyl]amine (113 mg, 0.29 mmol, prepared in example 1), phenyl boric acid (54 mg, 0.44 mmol), potassium carbonate (61 mg, 0.44 mmol), and tetrakis(triphenyl phosphine)Pd(0) (17 mg, 0.02 mmol) in a mixture of dioxane/water (3:1, 7 mL). The mixture was then heated at 100° C. with stirring for 18 hours. The reaction was then cooled to room temperature and poured into H2O. The mixture was extracted with EtOAc and the organic layer was washed twice with H2O, dried over anhydrous Na2SO4, filtered, and concentrated under reduced vacuum. The resulting semi-solid was purified via radial chromatography (Chromatotron, Harrison Research Inc., 840 Moana Court, Palo Alto, Calif. 94306) using a 2000 micron rotor (silica gel) and eluting with a solvent of Hexane/EtOAc 4:1 to provide the title compound (33 mg, 34%) as a slowly crystallizing tan oil. Ion spray M.S. 335 (M*+1).
