Procedure

To the solution of (R)-N-(1-azabicyclo[2.2.2]oct-3-yl)(5-(3-formylphenyl)thiophene-2-carboxamide) (875 mg) in methanol (15 mL), sodium borohydride (97.2 mg) was added. The mixture was then stirred at room temperature for 4 h. The residue was partitioned between water and chloroform. The extracts were dried over magnesium sulfate, filtered, and evaporated, and the residue was then purified by flash chromatography using 5–20% 3.5M methanolic ammonia/chloroform mixtures as the eluent to give the title compound (547 mg); MS (ES+) 343 (MH+).
