A solution of 2-biphenylcarboxylic acid (198 mg, 1 mmole), 1-methyl-3-(methylaminomethyl)-1H-indazole (210 mg, 1.2 mmole), EDC (230 mg, 1.2 mmole), HOBt.H2O (162 mg, 1.2 mmole), and triethylamine (0.28 mL, 2.0 mmole) in DMF (5 mL) was stirred at RT. After 18 hr, the reaction was concentrated to dryness, and the residue was purified by flash chromatography on silica gel (45% EtOAc/hexanes). The title compound (221 mg, 62%) was obtained as a white solid: MS (ES) m/e 356 (M+H)+.
