실험 절차

4′-[5-(Aminomethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide (Example 53) (30 mg), EDC (19.8 mg), HOBt (11.7 mg), 3-methyl-5-isoxazoleacetic acid (12.2 mg) and DIPEA (0.02 ml) were mixed in DMF (5 ml). The reaction was stirred at room temperature for 48 hours, the DMF evaporated under vacuum and the residue dissolved in DCM. The solution was washed with water (2×10 ml) and the DCM was evaporated under vacuum. The residue was dissolved in methanol and filtered through a bond-elut (SCX, 2 g). The solvent was evaporated from the filtrate and the residue applied to a bond-elut (silica) and eluted with an ethyl acetate/cyclohexane gradient to give, after evaporation of the solvent, N-cyclopropyl-6-methyl-4′-[5-({[(3-methylisoxazol-5-yl)acetyl]amino}methyl)-1,3,4-oxadiazol-2-yl]-1,1′-biphenyl-3-carboxamide.
