Reaction Steps

To the solution of (R)-N-(1-azabicyclo[2.2.2]oct-3-yl)(5-(3-cyanophenyl)thiophene-2-carboxamide) (311 mg) in methanol and acetic acid (1:1, 10 mL) a catalytic amount of 10% Pd—C was added and the mixture was hydrogenated at 50 p.s.i. for 36 hr. The mixture was filtered through a pad of celite. The residue was purified first 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 (23 mg); MS (ES+) 342 (MH+).
