A mixture of 2-(4-hydroxy-phenyl)-N-[1-(2-pyrrolidin-1-yl-ethyl)-1H-indazol-6-yl]-acetamide (45.0 mg, 0.124 mmol), 1-bromomethyl-4-fluoro-benzene (35.0 mg, 0.185 mmol), Cs2CO3 (60.0 mg, 0.184 mmol) in 2 mL of DMF was shaken for 6 hours and concentrated under reduced pressure. The residue was dissolved in a 1:1 mixture of dimethyl sulfoxide/MeOH (1.5 mL) and purified by preparative reverse-phase HPLC. 1H NMR (500 MHz, DMSO-D6) δ ppm 1.82 (m, 2 H), 1.98 (m, J=7.02, 7.02 Hz, 2 H), 3.02 (m, 2 H), 3.48 (m, 2 H), 3.68 (m, 4 H), 4.65 (t, J=6.24 Hz, 2 H), 5.07 (s, 2 H), 6.97 (m, 2 H), 7.11 (m, 1 H), 7.21 (m, 2 H), 7.27 (m, 2 H), 7.48 (m, 2 H), 7.71 (m, 1 H), 8.08 (s, 1 H), 8.26 (s, 1 H), 10.35 (s, 1 H); MS (ESI) m/z 473 [M+H]+.
