Reaction Steps

Palladium on activated carbon (0.010 g) was added to a solution of 4-(4-benzo[1,3]dioxol-5-yl-5-(6-methyl-pyridin-2-yl)-1H-imidazol-2-yl)-piperidine-1-carboxylic acid benzyl ester (0.100 g, 0.20 mmol; see Example 5) in methanol (5 mL). The reaction mixture was stirred under hydrogen atmosphere for 4 hours. The mixture was then filtered and concentrated to give 0.070 g (97%) of the title compound as a yellow oil.
