Versuchsvorschrift

3-Methyl-2-(5-phenyl-1,3,4-oxadiazol-2-ylamino)butanoic acid (80 mg, 0.3 mmol), EDCI (65 mg, 0.33 mmol), 4-(4-chlorophenyl)-piperidine hydrochloride (78 mg, 0.33 mmol) and HOBt (40 mg, 0.3 mmol) were combined and suspended in DMF (2 mL). Diisopropylethylamine (210 μL, 1.2 mmol) was added and the reaction was stirred at rt. overnight. After this time, methanol (2 mL) was added to the reaction and the mixture was purified directly by preparative HPLC to give 1-(4-(4-chlorophenyl)piperidin-1-yl)-3-methyl-2-(5-phenyl-1,3,4-oxadiazol-2-ylamino)butan-1-one (60 mg, 30%). MS found: 439 (M+H).
