Procedure

Prepared by a method analogous to that described in example 1 from (R)-N-(1-aza-bicyclo[2.2.2]oct-3-yl)(5-bromothiophene-2-carboxamide) and 3-formylphenyl boronic acid, tetrakis(triphenylphosphine)palladium(0), sodium carbonate in a mixture of tetrahydrofuran, ethanol and water. The compound was purified 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. The aqueous layer was extracted by chloroform and evaporated to gave the title compound; MS (ES+) 341 (MH+)
