Procedure

To a stirred solution of {[5-(2-benzyloxy-phenyl)-1H-pyrazole-3-carbonyl]-amino}-acetic acid (0.15 g, 0.00039 mol) in DMF (2 mL) was added DIPEA (0.224 g, 0.001736 mol), HOBt (0.065 g, 0.00048 mol) and EDCI.HCl (0.0925 g, 0.000482 mol) at ambient temperature. After 5 minutes (2-chlorophenoxy)-piperidin-4-yl-amine hydrochloride (0.1 g, 0.00041 mol) was added and the resulting mixture was stirred overnight. The reaction mixture was then diluted with cold water and the resulting precipitate was isolated by filtration and dried to afford 0.08 g (33%) of 5-(2-benzyloxy-phenyl)-1H-pyrazole-3-carboxylic acid {2-[4-(2-chloro-phenoxy)-piperidin-1-yl]-2-oxo-ethyl}-amide. LCMS: 544.2 (M+1)+, 99.03%.
