Procedure
The title compound was prepared from 120 mg of 1-(1-benzyl-piperidin-4-yl)-1-H-benzoimidazole (from Step A), 100 mg of 10% palladium on carbon and 100 mg of ammonium formate in 5 mL of MeOH using a procedure analogous to that described in Example 95, Step C to provide 70 mg of the title compound as a solid.
