A mixture of 3-chloro-1-(2-pyrrolidin-1-yl-ethyl)-1H-indazol-4-ylamine (300 mg, 1.14 mmol), (4-benzyloxy-phenyl)-acetic acid (302 mg, 1.25 mmol), ethyldimethylpropylcarbodiimide hydrochloride (261 mg g, 1.37 mmol), N-hydroxybenzotriazole (184 mg, 1.37 mmol), N-methyl morpholine (290 mg, 2.72 mmol) in 5 mL of DMF was stirred for 6 hours and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, triethylamine/ethyl acetate, 1/10) to provide the title compound. 1H NMR (300 MHz, DMSO-d6) ppm 1.60 (m, 4H), 2.43 (m, 4H), 2.85 (t, 2H, J=6.44), 3.69 (s, 2H), 4.48 (t, 2H, J=6.44), 5.10 (s, 2H), 6.99 (d, 2H, J=8.81), 7.28–7.48 (m, 9H), 7.59 (m, 1H), 10.10 (s, 1H); MS (DCI/NH3) m/z 489 [M+H]+.
