실험 절차

4′-[5-(Chloromethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide (Intermediate 45) (37 mg) and potassium iodide (5 mg) were mixed in cyclopropylmethylamine (3 ml) and the reaction stirred at room temperature for 18 hours. The excess amine was evaporated under vacuum and the residue purified by preparative HPLC. After evaporation of the solvent this gave N-cyclopropyl-4′-(5-{[(cyclopropylmethyl)amino]methyl}-1,3,4-oxadiazol-2-yl)-6-methyl-1,1′-biphenyl-3-carboxamide.
