Procedure

A solution of 2-[3-(2-Pyridin-2-yl-vinyl)-1H-indazol-6-ylamino]-benzoic acid (50.0 mg, 0.084 mmol), cyclobutylamine (18.2 μL, 0.17 mmol), triethylamine (58 μl, 0.42 mmol), dissolved in DMF (0.8 mL), was treated with HATU (48 mg, 0.13 mmol). The mixture was stirred overnight, then purified by reverse phase HPLC yielding 43.2 mg (92%) of the title compound as a TFA salt (1.5 H2O, 1.1 TFA, effective MW=561.92). 1H NMR (DMSO-d6): δ 9.78 (1H, s), 8.72 (2H, m), 8.13 (4H, m), 7.70 (1H, d, J=7.1), 7.58 (2H, m), 7.41 (2H, m), 7.27 (1H, s), 6.89 (1H, t, J=4.2), 2.84 (1H, m), 0.72 (2H, m), 0.56 (2H, m). ESIMS (M+H+): 396.1.
