2-(4-Benzyloxy-phenyl)-N-[1-(2-pyrrolidin-1-yl-ethyl)-1H-indazol-4-yl]-acetamide (Example 3, 500 mg, 1.10 mmol) and Pd (50 mg, 10% on carbon) were suspended in ethanol (40 mL) and stirred under a hydrogen atmosphere at room temperature for 6 hours. The mixture was filtered and the filtrate was concentrated under reduced pressure to provide the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 1.62 (m, 4H), 2.45 (m, 4H), 2.87 (t, 2H, J=6.78), 3.65 (s, 2H), 4.47 (t, 2H, J=6.78), 6.72 (m, 2H), 7.16 (m, 2H), 7.25–7.65 (m, 3H), 8.26 (s, 1H), 9.26 (s, 1H), 10.09 (s, 1H); MS (DCI/NH3) m/z 365 [M+H]+.
