Procedure

[3-(4-{2-(Piperidine-4-ylmethyl)-1-[4-(4-chloro-phenoxy)-phenyl]-1H-imidazol-4-yl}-phenoxy)-propyl]-diethyl-amine (Example 539) (0.1 mmol) was treated in anhydrous DCM (2 ml) with acetaldehyde (1.2 eq.,) followed by addition of Na(OAc)3BH (1.5 eq.). The reaction mixture was stirred at rt. Crude product was extracted into EtOAc and washed with saturated sodium bicarbonate solution. The organic layer was dried over anhydrous sodium sulfate and concenterated in vacuo to give desired product, which was purified by column chromatography on silica gel to afford 49 mg of Example 540.
