Reaction Steps
To a solution of 6-(3-amino-phenylamino)-1,3-dihydro-indol-2-one (120 mg, 0.50 mmol, prepared as described in Example 1) and 4-(4-ethyl-piperazin-1-ylmethyl)-3-trifluoromethyl-benzoic acid hydrochloride (213 mg, 0.60 mmol) in DMF (5 mL) is added N,N-diisopropylethylamine (437 μL, 2.5 mmol) followed by addition of HATU (191 mg, 0.50 mmol). The mixture is stirred at ambient temperature overnight. The mixture is diluted with EtOAc and washed with 10% Na2S2O3 aqueous solution and brine. The organic layer is separated, dried over MgSO4, and concentrated. The crude is purified by column chromatography (CH2Cl2/CH3OH=9:1) to give the desired compound. LC-MS: 538.2 (MH+).
