Procedure

The title compound (60 mg, 21%, white foam) was prepared from [2-(4-bromophenoxy)propyl][(methylethyl)sulfonyl]amine (275 mg, 0.818 mmol, prepared in example 1), 4-fluorobenzeneboronic acid (140 mg, 1.001 mmol), dichlorobis(triphenylphosphine)palladium(II) (23 mg, 0.033 mmol), 2 M sodium carbonate (295 mg in 1.4 mL water), and 1,2-dimethoxyethane (5.5 mL) in a manner analogous to the procedure described in Example 8. The crude material was purified utilizing a Chromatotron® with a 2000 μm rotor in a 1:1 hexane:ethyl acetate solvent system, yielding 310 mg of a co-eluting mixture of unreacted starting material and title compound. This mixture was further purified by reverse phase chromatography on a Vydac C-18 column on a gradient of 5 to 70% of 0.1% trifluoroacetic acid/acetonitrile in water over 45 minutes at 200 mL/min elution rate.
