実験手順

The product from Example 1, Step 2 (100 mg, 0.36 mmol, 1.0 equiv) was combined with 3-chloro-1H-indazol-5-amine (90 mg, 0.53 mmol, 1.5 equiv) and PS-carbodiimide resin (0.994 mmol/g loading, 564 mg, 0.53 mmol, 1.5 equiv) in 5 mL of DMF and reacted overnight at room temperature. The reaction mixture was filtered and washed alternately with MeOH and CH2Cl2 (twice), then with diethyl ether. The filtrate was concentrated en vacuo and redissolved in ethyl acetate. The solution was washed with 0.5 N HCl, 0.5 N NaOH, and satd. NaCl. The organic layer was concentrated en vacuo. The residue was triturated with methylene chloride/methanol/ethyl acetate to provide 20 mg (13%) of the title compound as a light pink powder. MS (ES+) m/e 431 [M+H]+.
