実験手順

(+,−) Trans propane-2-sulfonic acid [2-(4-iodo-phenyl)-cyclopentyl]-amide (356 mg, 0.91 mmol, prepared in example 2) and [4-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-acetonitrile (275 mg, 1.13 mmol) were treated as described in example 6. The product was chromatographed on Chromatotron® eluting with 99.5:0.5 methylene chloride:ethyl acetate to afford 237 mg (68%) of the title compound as a white solid. The NMR was consistent with the assigned structure.
