실험 절차

(−)-[2-Fluoro-2-(4-iodophenyl)propyl][(methylethyl)sulfonyl]amine (1.00 g, 2.6 mmol, prepared in example 1a), 4-carboxybenzene boronic acid (485 mg, 2.9 mmol), Na2CO3/H2O (4.4 mL, excess), tetrakis(triphenyl phosphine)palladium(0) (206 mg, 0.2 mmol) and dioxane (20 mL) were mixed together in a 50 mL single neck flask and stirred at 80° C. for 4 hours. The reaction was cooled to room temperature and poured into 1N HCl and the desired product was extracted with ethyl acetate. The organic layer was dried over MgSO4, filtered, and concentrated under reduced pressure to yield 871 mg as a foam. This material was purified via silica gel chromatography employing the chromatotron and using a 4000 micron rotor while eluting with a solvent of methylene chloride/methanol 9:1 to yield the title compound (500 mg, 51%) as a tan solid. Ion spray M.S. 378.1 (M*−1).
