Reaction Steps

Phenylacetic acid (12 mg) and HATU (33 mg) in DMF (1 ml) were stirred for 10 minutes at room temperature. To this solution was added HOBt (11.6 mg), DIPEA (.0.45 ml) and 4′-[5-(aminomethyl)-1,3,4-oxadiazol-2-yl]-N-cyclopropyl-6-methyl-1,1′-biphenyl-3-carboxamide (Example 53) (30 mg) in DMF (2 ml) and the reaction stirred at room temperature for 18 hours. The solvent was evaporated under vacuum and the residue dissolved in DMSO (0.25 ml), methanol (0.25 ml) was added and the precipitate produced isolated by filtration to give N-cyclopropyl-6-methyl-4′-(5-{[(phenylacetyl)amino]methyl}-1,3,4-oxadiazol-2-yl)-1,1′-biphenyl-3-carboxamide.
