实验步骤: To a solution of 4-[5-(1-oxo-2,3-dihydro-1H-isoindol-5-yl)-imidazo[1,2-a]pyridin-8-ylamino]-benzoic acid (37.0 mg, 0.096 mmol), 4-dimethylaminobenzylamine (15.91 mg, 0.106 mmol) and triethylamine (10.72 mg, 0.047 mL, 0.106 mmol) in dimethylformamide (0.4 mL) under nitrogen is added benzotriazole-1-yl-oxy-tris-pyrrolidino-phosphonium hexafluorophosphate (55.10 mg, 0.106 mmol). The reaction mixture is then stirred at room temperature for 18 hours. The mixture is then diluted with EtOAc and washed with saturated aqueous NaHCO3. The combined organic layers are dried (MgSO4) and the solvent is removed under reduced. The crude product is purified by reverse phase HPLC to yield the title compound. washed with saturated aqueous NaHCO3 The combined organic layers are dried (MgSO4) the solvent is removed The crude product is purified by reverse phase HPLC

实验步骤: 2′-Methyl-5′-(5-methyl-1,3,4-oxadiazol-2-yl)-1,1′-biphenyl-4-carboxylic acid (11.3 mg, 0.034 mmol), HOBT (6.0 mg, 0.044 mmol), 1-(3-dimethylaminopropyl)-3-ethyl carbodiimide hydrochloride (8.0 mg, 0.042 mmol) and 4-dimethylaminobenzylamine (0.34 mmol) were mixed in DMF (0.7 ml) and the reaction left at room temperature for 18 h. The DMF was evaporated under vacuum and the residue partitioned between DCM (0.4 ml) and water (0.4 ml). The organic phase was washed with aqueous sodium hydroxide (0.5M, 0.2 ml) and the DCM evaporated under vacuum. The residue was purified by mass directed HPLC to give N-(4-dimethylaminobenzyl)-2′-methyl-5′-(5-methyl-1,3,4-oxadiazol-2-yl)-1,1′-biphenyl-4-carboxamide. LCMS; retention time 2.98 min, MH+ 427. The DMF was evaporated under vacuum the residue partitioned between DCM (0.4 ml) and water (0.4 ml) The organic phase was washed with aqueous sodium hydroxide (0.5M, 0.2 ml) the DCM evaporated under vacuum The residue was purified by mass
