実験手順

Cyclopropylacetic acid (8.6 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 DCM and washed with water (2×4 ml). The organic phase was reduced to dryness and the residue purified by bond-elut (SCX, 5 g) eluting with methanol and methanolic ammonia. The methanolic ammonia fraction was further purified by preparative HPLC to give, after evaporation of the solvents, N-cyclopropyl-4′-(5-{[(cyclopropylacetyl)amino]methyl}-1,3,4-oxadiazol-2-yl)-6-methyl-1,1′-biphenyl-3-carboxamide.
