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, 0.00174 mol), HOBt (0.065 g, 0.00048 mol) and EDCI.HCl (0.0925 g, 0.00048 mol) at ambient temperature. After 5 minutes (2-chloro-phenyl)-piperidin-4-yl-amine dihydrochloride (0.1 g, 0.00041 mol) was added to the reaction mixture continued stirring at the same temperature for overnight. The reaction mixture was diluted with cold water, filtered the solid precipitated and dried to afford 0.205 g (98%) of 5-(2-benzyloxy-phenyl)-1H-pyrazole-3-carboxylic acid {2-[4-(2-chloro-phenylamino)-piperidin-1-yl]-2-oxo-ethyl}-amide. LCMS: 544.2 (M+1)+, 92.2%.
