A mixture of 1-(2-pyrrolidin-1-yl-ethyl)-1H-indazol-5-ylamine (60 mg, 0.26 mmol), (4-benzyloxy-phenyl)-acetic acid (63 mg, 0.26 mmol), ethyldimethylpropylcarbodiimide hydrochloride (60 mg g, 0.31 mmol), N-hydroxybenzotriazole (42 mg, 0.31 mmol), and N-methyl morpholine (66 mg, 0.62 mmol) in 2 mL of DMF was shaken for 6 hours. The mixture was concentrated under reduced pressure and the residue was dissolved in 1.5 mL of a 1:1 mixture of dimethyl sulfoxide/methanol and purified by preparative reverse-phase HPLC. 1H NMR (300 MHz, DMSO-d6) δ ppm 1.61 (m, 4H), 2.43 (m, 4H), 2.86 (t, 2H, J=6.78), 3.56 (s, 2H), 4.45 (t, 2H, J=6.78), 5.08 (s, 2H), 6.97 (m, 2H), 7.25–7.31 (m, 6H), 7.27 (m, 2H), 7.59 (m, 1H), 7.97 (s, 1H), 8.08 (s, 1H), 10.10 (s, 1H); MS (DCI/NH3) m/z 455 [M+H]+.
