Procedure

The product of Example 5, Step 2 (110 mg, 0.368 mmol, 1.00 equiv), 5-amino-3-bromoindazole (78 mg, 0.368 mmol, 1.0 equiv), and EDC (84 mg, 0.441 mmol, 1.20 equiv) were suspended in 1.0 mL DMF. Et3N (0.061 mL, 0.441 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) to provide 52 mg (29%) of the title compound as an off white solid. MS (ES+) m/e 494 [M+H]+
