The product of Example 1, Step 2 (180 mg, 0.64 mmol, 1.00 equiv), 5-amino-7-methylindazole (94 mg, 0.64 mmol, 1.0 equiv), and EDC (147 mg, 0.768 mmol, 1.20 equiv) were suspended in 1.5 mL DMF. Et3N (0.107 mL, 0.768 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 triturated with EtOAc and CH2Cl2, filtered, and washed with CH2Cl2 to provide 35 mg (13%) of the title compound as an off white solid. MS (ES+) m/e 434 [M+H]+
