실험 절차
A mixture of 3,7-dibromodibenzothiophene-5,5-dioxide (0.60 g, 1.75 mmol; see J. Med. Chem. 1978, 21, 1084), (S)-(−)-quinuclidin-3-ol (280 mg, 2.2 mmol; Acros), copper (I) iodide (33 mg, 0.17 mmol; Aldrich), 1,10-phenanthroline (63 mg, 0.35 mol; Aldrich) and powdered cesium carbonate (0.86 g, 2.64 mmol; Aldrich) in toluene (2 mL) was heated to 110° C. with vigorous stirring for 30 h. After cooling to room temperature, the reaction mixture was filtered through diatomaceous earth, rinsing with ethyl acetate and dichloromethane, and the residue purified by flash chromatography (80 g silica gel, 1:10:89 NH4OH-MeOH—CH2Cl2) to afford the title compound (0.37 g, 1.08 mmol; 63% yield): MS (DCI/NH3): m/z 342 (M+1)+.
