Reaction Steps

The product from Example 45, Step 2 (215 mg, 0.649 mmol, 1.00 equiv), 5-amino-3-methylindazole (96 mg, 0.649 mmol, 1.0 equiv), and EDC (149 mg, 0.779 mmol, 1.20 equiv) were suspended in 1.5 mL DMF. Et3N (0.109 mL, 0.779 mmol, 1.2 equiv) was added and the solution was stirred at room temperature for 18 hrs. 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 (0-80% EtOAc in Hexanes) to provide 70 mg (23%) of the title compound as a white solid. MS (ES+) m/e 461 [M+H]+
