The product from Example 3, Step 2 (103 mg, 0.36 mmol, 1.0 equiv) was combined with 3-chloro-1H-indazol-5-amine (91 mg, 0.54 mmol, 1.5 equiv) and PS-carbodiimide resin (0.994 mmol/g loading, 580 mg, 0.54 mmol, 1.5 equiv) in 6 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 EtOAc. The solution was washed with 0.5 N HCl, 0.5 N NaOH and satd. NaCl. The organic layer was concentrated en vacuo. Following purification by flash chromatography (0-50% EtOAc in CH2Cl2), the solid was triturated with CH2Cl2 to provide 10 mg (6.5%) of the title compound as light pink crystals. MS (ES+) m/e 434 [M+H]+.
