Reaction Steps

In analogy to the procedure described for the synthesis of 4-benzyl-piperidine-4-carboxylic acid (pyridin-3-ylmethyl)-amide; hydrochloride (intermediate 1) the title compound was prepared from 4-(4-chloro-benzyl)-piperidine-1,4-dicarboxylic acid mono-tert-butyl ester (commercially available) and benzylamine (commercially available) with subsequent cleavage of the protecting group under acidic conditions. The title compound was purified on silica eluting with a gradient formed from DCM and 2N NH3 and methanol. MS (m/e): 236.1/343.2 (MH+).
