Procedure

The product of step 2 (146 mg, 0.512 mmol, 1.00 equiv), 1H-indazol-5-amine (68 mg, 0.512 mmol, 1.00 equiv) and EDC (118 mg, 0.615 mmol, 1.20 equiv) were suspended in 8.0 mL DMF. Et3N (0.086 mL, 0.615 mmol, 1.20 equiv) was added and the solution was stirred overnight at room temperature. The reaction mixture was diluted with EtOAc and 1N HCl. The phases were separated, and the organic phase was washed twice with 1N HCl, once with satd. NaHCO3, and once with satd. NaCl. The organic phase was dried over Na2SO4, filtered, and concentrated en vacuo. The residue was purified by flash chromatography (100% EtOAc) to provide 0.070 g (33%) of the title compound as a white solid. MS (ES+) m/e 415 [M+H]+
