실험 절차

4′-[5-(Aminomethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide (Example 53) (30 mg), HOBt (11.7 mg), EDC (19.8 mg), DIPEA (0.018 ml) and glycolic acid (6.6 mg) were mixed in DCM (6 ml) and methanol (1 ml) and the reactions stirred at room temperature for 96 hours. The reaction was reduced to dryness under vacuum and the residue partitioned between DCM and water. The organic phase was evaporated and the residue purified by bond-elut (silica, 5 g) eluting with an ethyl acetate/cyclohexane gradient and then by preparative HPLC to give, after evaporation of the solvents, N-cyclopropyl-4′-{5-[(glycoloylamino)methyl]-1,3,4-oxadiazol-2-yl}-6-methyl-1,1′-biphenyl-3-carboxamide.
