Reaction Steps

To a solution of (R)-N-(1-azabicyclo[2.2.2]oct-3-yl)(5-bromothiophene-2-carboxamide) (463 mg) in pyridine (10 mL) phenol (158 mg), copper iodide (32 mg) and potassium carbonate (97 mg) were added. The mixture was stirred at 125° C. for 65 h under nitrogen. Water was added and the aqueous layer was extracted with chloroform. Following evaporation, the residue was purified by flash chromatography using 5-20% 3.5M methanolic ammonia/chloroform mixtures as the eluent and then by reverse phase HPLC on a Waters Bondapak® C18 column using a gradient of acetonitrile and 0.1% aqueous trifluoroacetic acid as the eluent. The free base was prepared by basification of the product-containing fractions and extraction into chloroform followed by evaporation to gave the title compound (80 mg); MS (ES+) 329 (MH+).
