Procedure

To a stirred solution of {[5-(2-benzyloxy-phenyl)-isoxazole-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, 0.000482 mol) and EDCI.HCl (0.0925 g, 0.00048 mol) at ambient temperature. After 5 minutes 4-(2-chloro-phenylamino)-piperidine dihydrochloride (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. Purification by column chromatography using basic alumina (50% ethyl acetate in hexane) afforded 0.142 g (78%) of 5-(2-benzyloxy-phenyl)-isoxazole-3-carboxylic acid {2-[4-(2-chloro-phenylamino)-piperidin-1-yl]-2-oxo-ethyl}-amide.
