実験手順

The product of Example 1, Step 2 (115 mg, 0.409 mmol, 1.00 equiv), 5-amino-3-bromoindazole (87 mg, 0.409 mmol, 1.0 equiv), and EDC (94 mg, 0.491 mmol, 1.20 equiv) were suspended in 1.0 mL DMF. Et3N (0.068 mL, 0.491 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 47 mg (24%) of the title compound as an off white solid. MS (ES+) m/e 476 [M+H]+
