Versuchsvorschrift

The product of Example 5, Step 2 (225 mg, 0.75 mmol, 1.00 equiv), 5-amino-3-methylindazole (110 mg, 0.75 mmol, 1.0 equiv), and EDC (172 mg, 0.90 mmol, 1.20 equiv) were suspended in 2.0 mL DMF. Et3N (0.125 mL, 0.90 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 (20-100% EtOAc in Hexanes) and further purified by reverse-phase HPLC (10-70% CH3CN/H2O—NH4OH to pH 10 over 20 minutes, retention time 11.74 min) to provide 18 mg (6%) of the title compound as a white solid. MS (ES+) m/e 429 [M+H]+
