Procedure

4′-{3-[(3R)-3-Aminopyrrolidinyl]propoxy}[1,1′-biphenyl]-4-carbonitrile (200 mg, 0.74 mmol), (3R)-3-pyrrolidinol (70 mg, 0.81 mmol), potassium carbonate (152 mg) and potassium iodide (183 mg) in 25 mL of 2-butanone were heated at 110° C. for 72 hours. The mixture was evaporated under reduced pressure and the residue was purified by chromatography (CHCl3:MeOH:NH4OH, 9:1:0.1) to provide the title compound (69 % yield).
