Versuchsvorschrift

The product of Example 21, Step 2 (165 mg, 0.52 mmol, 1.00 equiv), 5-amino-7-methylindazole (77 mg, 0.52 mmol, 1.0 equiv), and EDC (119 mg, 0.624 mmol, 1.20 equiv) were suspended in 1.5 mL DMF. Et3N (0.087 mL, 0.624 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 77 mg (33%) of the title compound as an off white solid. MS (ES+) m/e 447 [M+H]+
