Procedure

50 mg (0.21 mmol) of 3-(5-oxo-4-phenyl-4,5-dihydro-[1,3,4]oxadiazol-2-yl)-propionic acid, 245 mg (2.13 mmol) of NEM and 77 mg (0.23 mmol) of TOTU were dissolved in 2 ml of DMF and stirred at room temperature for 15 min. 20 mg (0.23 mmol) of piperidine were added, and the reaction mixture was stirred at room temperature for 16 h. After evaporation, the product was purified by silica gel chromatography. Yield: 45 mg.
