A mixture of 1-(2-dimethylamino-ethyl)-1H-indazol-5-ylamine (42 mg, 0.20 mmol), 4-phenoxy-phenylacetic acid (47 mg, 0.21 mmol), ethyldimethylpropylcarbodiimide hydrochloride (43 mg g, 0.22 mmol), N-hydroxybenzotriazole (30 mg, 0.22 mmol), N-methyl morpholine (46 mg, 0.44 mmol) in 2 mL of DMF was shaken for 6 hours. The mixture was concentrated under reduced pressure, the residue taken up in 1.5 mL of a 1:1 mixture of DMSO/MeOH and purified by preparative reverse-phase HPLC. 1H NMR (300 MHz, DMSO-d6) ppm 2.84 (s, 6H), 3.65 (s, 2H), 3.62 (t, J=6.24, 2H), 4.76 (t, J=6.24, 2H), 6.97–7.00 (m, 4H), 7.11–7.14 (m, 1H), 7.36–7.40 (m, 4H), 7.64 (m, 1H), 7.69 (m, 1H), 8.12 (m, 1H), 8.15 (m, 1H), 9.58 (s, 1H); MS (DCI/NH3) m/z 415 [M+H]+.
