Procedure
DIPEA (130 μl, 1.0 mmol) was added to a solution of 2′-methyl-5′-(5-methyl-1,3,4-oxadiazol-2-yl)-1,1′-biphenyl-4-carboxylic acid (100 mg, 0.34 mmol), 3-diethylaminopropylamine (49 mg, 0.37 mmol), HBTU (155 mg, 0.41 mmol) and HOBT (46 mg, 0.34 mmol) in DMF (1.0 ml). The reaction was stirred at room temperature for 66 h. The DMF was evaporated under vacuum and the residue partitioned between DCM (5 ml) and water (5 ml) The organic phase was absorbed onto a silica flash column and eluted with DCM/ethanol/ammonia (100:8:1). The product fractions were concentrated under vacuum to give N-[3-(diethylamino)propyl]-2′-methyl-5′-(5-methyl-1,3,4-oxadiazol-2-yl)-1,1′-biphenyl-4-carboxamide (88 mg, 64%).
